Question

What is the standard form of # y=(x + 2)(x + 2)-x^3+(x-3)^2 #?

Answer 1

color(indigo)(y = -x^3 + 2x^2 -2x + 13# is the standard form

Explanation:

`y = (x+2) (x+2) - x^3 + (x - 3)^2`

`y = (x+2)^2 - x^3 + (x-3)^2`

`y = x^2 + 4x + 4 - x^3 + x^2 - 6x + 9`

`color(indigo)(y = -x^3 + 2x^2 -2x + 13` is the standard form
