$y = 6x^3-10x^2-4x$

To find the standard form of a polynomial , we simply multiply all given factors and group like terms.

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

$=2(3x^3-5x^2-2x)$

$=6x^3-10x^2-4x$

Thus we have the standard form:

$y = 6x^3-10x^2-4x$

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