Work Step by Step

You are given $w^{2}$-14wz+40$z^{2}$. Factor it out: $w^{2}$-10wz-4wz+40$z^{2}$ -break out the middle value- ($w^{2}$-10wz)+(-wz+40$z^{2}$) -group the first two and last two terms- w(w-10z)-4z(w-10z) -Find the GCF of each grouping's- (w-4z)(w-10z) -factor out the common term- =(w-4z)(w-10z)
