We have L. Therefore, can be written as:. This equation is of type:. Hence, the given equation is a quadratic equation. Q1 ii Check whether the following are quadratic equations :. Given equation can be written as:.

Q1 iii Check whether the following are quadratic equations :. S can be written as:. The equation is of the type:. Q1 iv Check whether the following are quadratic equations :. Q1 v Check whether the following are quadratic equations :. Q1 vi Check whether the following are quadratic equations :. This equation is NOT of type:.

Q1 vii Check whether the following are quadratic equations :. Hence, the given equation is not a quadratic equation. Q1 viii Check whether the following are quadratic equations :. Q2 i Represent the following situations in the form of quadratic equations : The area of a rectangular plot is. The length of ncert 10th maths chapter 4 solutions inc plot in meters is one more than twice its breadth. We need to find the length and breadth of the plot.

Given the area of a rectangular plot is. Let the breadth of the plot be. Then, the length of the plot will be:. Therefore the area ncert 10th maths chapter 4 solutions inc be:.

Hence, the length and breadth of the plot will satisfy the equation. Q2 ii Ncert 10th maths chapter 4 solutions inc the following situations in the form of quadratic equations : The product of two consecutive positive integers is We need to find the integers. Given the product of two consecutive integers is. Let two consecutive integers be.

Then, their product will be:. Hence, the two consecutive integers will satisfy this quadratic equation. The product of their ages in years 3 years from now will be Let the age of Rohan be years.

Then his mother age will be: years. After three years. Rohan's age will be years and his mother age will be years. Then according to question. The product of their ages 3 years from now will be:. Hence, the age of Rohan satisfies the quadratic equation. Q2 iv Represent the following situations in the form of quadratic equations : A train travels a distance of km at a uniform speed.

We need to find the speed of the train. The distance to be covered by the train is. The time taken will be. If the speed had been less, the time taken would be:. Now, according to question. Dividing by 3 on both the. Hence, the speed of the train satisfies the quadratic equation. Q1 i Find the roots of the following quadratic equations by factorization:.

Given the quadratic equation:. Factorization gives. Hence, the roots of the given quadratic equation are. Q1 ii Find the roots of the following quadratic equations by factorization:.

Factorisation gives. Q1 iii Find the roots of the following quadratic equations by factorization:. Q1 iv Find the roots of the following quadratic equations by factorization:. Solving the quadratic equations, we. Q1 v Find the roots of the following quadratic equations by factorization:. Q2 Solve the problems given in Example 1. From Example 1 we get:.

Solving by factorization method:. Therefore, John and Jivanti have 36 and 9 marbles respectively in the beginning. Therefore, the ncert 10th maths chapter 4 solutions inc of toys on that day.

Q3 Find two numbers whose sum is 27 and the product is Let two numbers be x and y. Then, their sum will be equal to 27 and the product equals From equation 2 we have:.

Then putting the value of y in equation 1we ncert 10th maths chapter 4 solutions inc. Solving this equation:. Hence, the two required numbers are. Q4 Find two consecutive positive integers, the sum of whose squares is Let the two consecutive integers be. Then the sum of the squares is Hence, the two consecutive integers are.

Q5 The altitude of a right triangle is 7 cm less than its base. If the hypotenuse is 13 cm, find the other two sides.

Let the length of the base of the triangle be. Then, the altitude length will be:. Given if hypotenuse is. Applying the Pythagoras theorem; we. But, the length of the base cannot be negative.

Hence the base length will be. Therefore, we. Altitude length and Base length. Q6 A cottage industry produces a certain number of pottery articles in a day. It was observed on a particular day that the cost of production of each article in rupees was 3 more than twice the number of articles produced on that day. If the total cost of production on that day was Rs 90, find the number of articles produced and the cost of each article. Let the number of articles produced in a day.

The cost of production of each article will be. Given the total production on that day. Hence we have the equation. But, x cannot be negative as it is the number of articles. Therefore, and the cost of each article. Hence, the number of articles is 6 and the cost of each article is Rs. Q1 i Find the roots of the following quadratic equations, if they exist, by the method of completing the square. Given equation:.

Find her marks in the two subjects. There are three algebraic methods for finding the solution of a quadratic equation. We need to find the speed of the train. All concepts of quadratic equations and formulas have been explained well. If the difference of their perimeters is 24 m, find the sides of the two squares. We know that the area of a rectangle can be expressed as the product of its length and breadth.

Simply said:

You might need to take in to comment shopping vessel structure kits possibly upon or off line. (well being as well as safety). A mom competence be in a area as well as is simply watchful in your depart to process a tot. We have been ncery of trophy-sized fish, strips 1.
