Factor:
x%5E2%2B16%2B8x
It is customary to write polynomials in order of descending powers of the variable.
x%5E2%2B8x%2B16 Notice that the first term %28x%29%5E2 and last term %284%29%5E2 are perfect squares.
The factors are:
x%5E2%2B8x%2B16+=+%28x%2B4%29%28x%2B4%29
This can be written as:
%28x%2B4%29%5E2
