help please

(5x3−4x2−2x)(x+1)

=(5x3+−4x2+−2x)(x+1)

=(5x3)(x)+(5x3)(1)+(−4x2)(x)+(−4x2)(1)+(−2x)(x)+(−2x)(1)

=5x4+5x3−4x3−4x2−2x2−2x

=5x4+x3−6x2−2x

Hi Katie-Leigh    :))

(5x^3-4x^2-2x)

       (x+1)

$\frac{5x^3-4x^2-2x}{x+1}\\ =\frac{x(5x^2-4x-2)}{x+1}\\$

There is nothing much you can do with this ://
