Question

What is the value of 3 x squared minus 5 x y + 5 y squared for x = negative 6 and y = 2?

Answer 1

188

Explanation:

3 * -6^2 - 5*-6*2 + 5*2^2

108 + 60 + 20= 188

Answer 2

A = 188

Explanation:

+ replace x = -6 and y= 2 into 3 x squared minus 5 x y + 5 y squared = A

So A= 3x^2 - 5xy + 5y^2

A = 3 *(-6)^2 -5* (-6) *2 +5* 2^2

A = 3* 36 +60 + 5*4

A= 108 +60 +20

or A = 188
