Question 42609
Factor:
{{{x^2+16+8x}}}
It is customary to write polynomials in order of descending powers of the variable.
{{{x^2+8x+16}}} Notice that the first term {{{(x)^2}}} and last term {{{(4)^2}}} are perfect squares.

The factors are:
{{{x^2+8x+16 = (x+4)(x+4)}}}
This can be written as:
{{{(x+4)^2}}}
