8x%5E3%2B64x%5E2%2B8x%2B64 Start with the given expression


%288x%5E3%2B64x%5E2%29%2B%288x%2B64%29 Group the terms in two pairs


8x%5E2%28x%2B8%29%2B8%28x%2B8%29 Factor out the GCF 8x%5E2 out of the first group. Factor out the GCF 8 out of the second group


%288x%5E2%2B8%29%28x%2B8%29 Since we have the common term x%2B8, we can combine like terms


So 8x%5E3%2B64x%5E2%2B8x%2B64 factors to %288x%5E2%2B8%29%28x%2B8%29


In other words, 8x%5E3%2B64x%5E2%2B8x%2B64=%288x%5E2%2B8%29%28x%2B8%29
