exraven Group TitleBest ResponseYou've already chosen the best response.0
\[4x  x^2 = (x^2  4x)\]\[= (x^2  4x)  4 + 4\]\[= (x^2  4x + 4) + 4\]\[= 4  (x^2  4x + 4)\]\[= 4  (x  2)^2\]\[\int\limits x^3 \sqrt{4x  x^2}dx = \int\limits x^3 \sqrt{4  (x  2)^2} dx\]there i already completed the square for you, just do trig subs and you'll be fine
