First, use the FOIL method.
\n" ); document.write( " $\"%28x-1%29%28x%2B6%29=x%5E2%2B6x-x-6\"$
\n" ); document.write( " $\"%28x-1%29%28x%2B6%29=x%5E2%2B5x-6\"$
\n" ); document.write( " $\"%28x-1%29%28x%2B6%29=x%5E2%2B5x-6\"$
\n" ); document.write( "Then complete the square.
\n" ); document.write( "Don't worry about the 2 multiplier, we'll put it in later.
\n" ); document.write( " $\"%28x-1%29%28x%2B6%29=x%5E2%2B5x%2B%285%2F2%29%5E2-%285%2F2%29%5E2-6\"$
\n" ); document.write( " $\"%28x-1%29%28x%2B6%29=%28x%2B5%2F2%29%5E2-%2825%2F4%29-%2824%2F4%29\"$

\n" ); document.write( "Now put it the 2.
\n" ); document.write( " $\"2%28x-1%29%28x%2B6%29=2%28x%2B5%2F2%29%5E2-%2849%2F2%29\"$
