Question

If x =-2 and y = 2, the value of x² + y² is

Answer 1

Answer:

x=-2 & y=2 then x^2+y^2=(-2)^2+(2)^2=4+4=8

Answer 2

Given,

The value of x = -2 and y = 2.

To find,

The value of x² + y².

Solution,

We can easily solve this problem by following the given steps.

According to the question,

We have the following values:

x = -2 and y = 2

Now, put these values of x and y in the following expression:

x² + y²

(-2)²+(2)²

(Note that the product of two negative integers is always positive. And the square is to be solved by multiplying the same number two times. For example, the square of 3 is 9 and that of 4 is 16.)

4+4

8

Hence, the value of (x² + y²) is 8.
