The standard form is $y = 3x^3 +3x^2+6x$

We can multiply/expand the expression to get the standard form like this

$y = x( 3x-3)(x+2)$

Step 1: Multiply the last two factor, and combine like terms

$y = x(3x^2 +6x -3x -6)$

$y= x(3x^3 +3x-6)$

Step 2: Distribute the "x" to get

$y = 3x^3 +3x^2+6x$

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