$\"%28x+%2B+4%29%5E2+-+9+=+0\"$ --> $\"%28x+%2B+4%29%5E2+=+9\"$ (adding 9 to both sides of the equal sign)
\n" ); document.write( " $\"%28x+%2B+4%29%5E2+=+9\"$ --> $\"abs%28x%2B4%29=sqrt%289%29=3\"$ (taking square root of both sides)
\n" ); document.write( " $\"abs%28x%2B4%29=3\"$ --> $\"x%2B4=3\"$ or $\"-%28x%2B4%29=3\"$ <--> $\"x%2B4=-3\"$
\n" ); document.write( " $\"x%2B4=3\"$ --> $\"x=-4%2B3=-1\"$
\n" ); document.write( " $\"x%2B4=-3\"$ --> $\"x=-4-3=-7\"$
\n" ); document.write( "The solutions are $\"highlight%28x=-1%29\"$ and $\"highlight%28x=-7%29\"$ \n" ); document.write( "
