Question

Determain the value of y, if x is -11.
Y=x^2-2

Answer 1

Given:

Y = x²-2

To find:

The value of y

Solution:

As given, x = -11.

• First of all, we have to apply the values.
• Value of x = -11
• X² = -11 x (-11)

= 121

• Y = 121-2
• Y = 119

Therefore, the value of y is 119.

Answer 2

y=119

Explanation:

11^2-2 =119

-11^2 goes into -11×-11

then do 11x11= 121

y=x^2-2

121-2=119
