Solve for x:
\n" ); document.write( "1)
\n" ); document.write( "\"%28x%2B5%29%5E2+=+7\" The short method: Take the square root of both sides.
\n" ); document.write( "\"x%2B5+=+sqrt%287%29\" and \"x%2B5+=+-sqrt%287%29\" Subtract 5 from both sides of each equation.
\n" ); document.write( "\"x+=+-5%2Bsqrt%287%29\" and \"x+=+-5-sqrt%287%29\"
\n" ); document.write( "\"%28x%2B5%29%5E2+=+7\" The long method: Expand the left side of the equation.
\n" ); document.write( "\"x%5E2%2B10x%2B25+=+7\" Subtract 7 from both sides.
\n" ); document.write( "\"x%5E2%2B10x%2B18+=+0\" Solve by the quadratic formula:\"x+=+%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F2a\"
\n" ); document.write( "\"x+=+%28-10%2B-sqrt%2810%5E2-4%281%29%2818%29%29%29%2F2%281%29\" Simplify.
\n" ); document.write( "\"x+=+%28-10%2B-sqrt%28100-72%29%29%2F2\"
\n" ); document.write( "\"x+=+%28-10%2B-sqrt%2828%29%29%2F2\"
\n" ); document.write( "\"x+=+%28-10%2B-2%2Asqrt%287%29%29%2F2\"
\n" ); document.write( "\"x+=+-5%2Bsqrt%287%29\" and \"x+=+-5-sqrt%287%29\"
\n" ); document.write( "Try the others like this!
\n" ); document.write( "
\n" );
