Answer
28(h+2)(h-1)
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)
