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

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

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

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