Solve for x:
\n" ); document.write( " $\"3x%5E2-8+=+100\"$ Add 8 to both sides of the equation.
\n" ); document.write( " $\"3x%5E2+=+108\"$ Now divide both sides by 3.
\n" ); document.write( " $\"x%5E2+=+36\"$ Finally, take the square root of both sides.
\n" ); document.write( " $\"sqrt%28x%5E2%29+=+sqrt%2836%29\"$
\n" ); document.write( " $\"x+=+6\"$ and $\"x+=+-6\"$ \n" ); document.write( "

\n" );
