The area of a triangle is
\n" ); document.write( " $\"A=bh%2F2\"$
\n" ); document.write( "Let’s substitute for the known values,
\n" ); document.write( " $\"x%5E2%2B5x%2B6=b%28x%2B3%29%2F2\"$
\n" ); document.write( "We can recognize that the area can be simplified into its factors.
\n" ); document.write( " $\"x%5E2%2B5x%2B6=%28x%2B2%29%28x%2B3%29\"$
\n" ); document.write( "We can again substitute,
\n" ); document.write( " $\"%28x%2B2%29%28x%2B3%29=b%28x%2B3%29%2F2\"$
\n" ); document.write( " $\"%28x%2B2%29cross%28%28x%2B3%29%29=b%2Across%28%28x%2B3%29%29%2F2\"$
\n" ); document.write( " $\"b=2%28x%2B2%29\"$
\n" ); document.write( " \n" ); document.write( "
