If the sum of the squares of x and y is 34, then find the product of x and y. Product of x and y is 15 in both cases. The difference between two positive numbers is 5 and the sum of their squares is Find the product of these numbers.

Let the two positive numbers be a and b. Given difference between them is 5 and sum of squares is Squaring on both sides gives. So, the product of numbers is Use property to evaluate:. Thus from equations 1 , 2 and 3 , we have.

The sum of two numbers is 9 and their product is Find the sum of their. Given sum of two numbers is 9 and their product is Let the numbers be a and b. Cubing on both sides gives. So the sum of cubes is If the difference of these numbers is 5 and their product is 24, find:. So, difference of their cubes is Cubing both sides, we get.

So, sum of their cubes is Dividing by x, we have. Given 3x -. We need to find. Given that. We need to find the value of. Consider the given equation:. By cross multiplication,. Dividing both sides by x,. Cubing both sides,. Hence proved. The sum of two numbers is 7 and the sum of their cubes is , find the sum of their square. Let a, b be the two numbers. The difference between two positive numbers is 4 and the difference between their cubes is Given difference between two positive numbers is 4 and difference between their cubes is Sum of their squares is Using identity:.

Using suitable identity, evaluate. Prove that:. Since square of any number is positive, the given equation is always positive.

In result ii , replacing b by -b, we get. Enter the OTP sent to your number Change. Resend OTP. Starting early can help you score better! Avail Offer. Chapter 4 - Expansion Exercise Ex. Question 2.
