$\frac{x^2+32x-45+256-256+x^3}{x+7}$
Learn how to solve polynomial factorization problems step by step online. Factor by completing the square (x^3+x^232x+-45)/(x+7). Add and subtract \displaystyle\left(\frac{b}{2a}\right)^2. Factor the perfect square trinomial x^2+32x+256. Subtract the values -45 and -256. Expand.
