Question

What is the standard form of `y= (2x-2)(2x+2)(-x+8)`?

Answer 1

`y` = `-4x^3+32x^2+4x-32`

Explanation:

Standard form of equation `y=(2x−2)(2x+2)(−x+8)` can be got by multiplying them and combining like terms.

`y=(2x−2)(2x+2)(−x+8)`

= `((2x)^2-2^2)(-x+8)`

= `(4x^2-4)(-x+8)` ie

`y` = `-4x^3+32x^2+4x-32`
