$y = 3x^3 - 9x^2$

Or

$y = 3x^3 - 9x^2 + 0x + 0$

To put this in standard form expand the term in parenthesis on the right side of the equation:

$y = 3x^2(x - 3)$ becomes:

$y = (3x^2 xx x) - (3x^2 xx 3)$

$y = 3x^3 - 9x^2$

Or

$y = 3x^3 - 9x^2 + 0x + 0$

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