You can put this solution on YOUR website!
$\"%28x+%2B+4%29%5E2+=+16\"$
\n" ); document.write( " $\"sqrt%28%28x+%2B+4%29%5E2%29+=+sqrt%2816%29\"$ Take the square root of both sides.
\n" ); document.write( " $\"x%2B4=4\"$ and $\"x%2B4=-4\"$ since both $\"4%2A4=%28-4%29%2A%28-4%29=16\"$
\n" ); document.write( "Solve the two equations for x.
\n" ); document.write( " $\"x%2B4=4\"$
\n" ); document.write( " $\"x%2B4-4=4-4\"$
\n" ); document.write( " $\"highlight%28x=0%29\"$
\n" ); document.write( " $\"x%2B4=-4\"$
\n" ); document.write( " $\"x%2B4-4=-4-4\"$
\n" ); document.write( " $\"highlight%28x=-8%29\"$
\n" ); document.write( "Your two solutions are x=0 and x=-8. \n" ); document.write( "
