Solve for x:
\n" ); document.write( " $\"%282x%2B5%29%5E2+=+49\"$ Take the square root of both sides of the equation.
\n" ); document.write( " $\"%282x%2B5%29+=+7\"$ or $\"%282x%2B5%29+=+-7\"$ Subtract 5 from both sides of each equation.
\n" ); document.write( " $\"2x+=+2\"$ or $\"2x+=+-12\"$ Divide both sides of each equation by 2.
\n" ); document.write( " $\"highlight%28x+=+1%29\"$ or $\"highlight%28x+=+-6%29\"$ \n" ); document.write( "

\n" );
