Solve for x:
\n" ); document.write( " $\"x%282x%2B7%29+=+-5\"$ Apply the distributive property on the left side.
\n" ); document.write( " $\"2x%5E2%2B7x+=+-5\"$ Add 5 to both sides.
\n" ); document.write( " $\"2x%5E2%2B7x%2B5+=+0\"$ Factor.
\n" ); document.write( " $\"2x%2B5%29%28x%2B1%29+=+0\"$ Appy the zero product principle.
\n" ); document.write( " $\"2x%2B5+=+0\"$ and/or $\"x%2B1+=+0\"$
\n" ); document.write( " $\"2x%2B5+=+0\"$ Subtract 5 from both sides.
\n" ); document.write( " $\"2x+=+-5\"$ Divide both sides by 2.
\n" ); document.write( " $\"x+=+-5%2F2\"$ This is one solution.
\n" ); document.write( " $\"x%2B1+=+0\"$ Subtract 1 from both sides.
\n" ); document.write( " $\"x+=+-1\"$ This is the other solution. \n" ); document.write( "

\n" );
