Work Step by Step

You are given $28h^{2}$+28h-56. Factor it out: 28($h^{2}$+h-2) -factor out the common factor of 28- 28($h^{2}$+2h-h-2) -break out the middle value- 28($h^{2}$+2h)(-h-2) -group the first two and last two terms- 28(h(h+2)-1(h+2) -Find the GCF of each grouping's- 28(h+2)(h-1) -factor out the common term- =28(h+2)(h-1)
