i just forgot how to solve quadratics and was wondering if anyone could help me on a question it is quite easy.

(x+3)(x-2)^2= 72

(x-2)^2

=x^2-4x+4

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

x^3-4x^2+4x+3x^2-12x+12

=x^3-x^2-8x+12= 72

im not quite sure what i should do next if i havent made any mistakes so far.

thankyou,
