Answer 2

Answer:

Hello friends!

Question:-

If x = 152, y = -91 find the value of 9x^2 + 30xy + 25y^2

To find:-

The value of 9x^2 + 30xy + 25y^2 is ?

Solution:-

In question it is given that x = 152 and y = -91.

So, if we have to find the value of 9x^2 + 30xy + 25y^2, then we have to put the value in their places.

Let's solve the problem

We have,

9x^2 + 30xy + 25y^2.

➡ 9(152)^2 + 30(152)(-91) + 25(-91)^2

➡ 9(23104) + 30(152)(-91) + 25(8281)

➡ 9(23104) + 30(-13832) + 25(8281)

➡ 207936 - 414960 + 207025

➡ 414961 - 414960

➡ 1 Ans.

Answer:-

Hence, the value of 9x^2 + 30xy + 25y^2 is 1.
