Find the value of

$3 x^{2}-2 y^{2}$
if x=-2 and y=2

Given: If $x = -2$ and  $y = 2$

To find :The value of $3x^{2} - 2y^{2}$

Answer:

$ x = -2 and  y = 2$ 

Substituting these values in the expression below

$3x^{2} - 2y^{2}$

= $3(-2)^{2} - 2(2)^{2}$

= 12 - 8 = 4

=$3x^{2} - 2y^{2} = 4$ when x = -2 and y = 2
