You can put this solution on YOUR website!
Your question will be written as,
\n" ); document.write( " $\"+sqrt%285x%5E2-9%29+=+2x+\"$
\n" ); document.write( "

\n" ); document.write( "Then taking the square root to the other side we get,
\n" ); document.write( " $\"+%285x%5E2-9%29+=+%282x%29%5E2+\"$
\n" ); document.write( "

\n" ); document.write( " $\"+%285x%5E2-9%29+=+%284x%5E2%29+\"$
\n" ); document.write( "

\n" ); document.write( "Taking (4x^2) to the other side we get,
\n" ); document.write( " $\"+%285x%5E2+-+4x%5E2+-+9%29+=+0+\"$
\n" ); document.write( "

\n" ); document.write( "Which then gives us,
\n" ); document.write( " $\"+%28x%5E2+-9%29+=+0+\"$
\n" ); document.write( "

\n" ); document.write( "Taking 9 to the other side we get,
\n" ); document.write( " $\"+%28x%5E2%29+=+9+\"$
\n" ); document.write( "

\n" ); document.write( "Taking square root on both sides we get,
\n" ); document.write( " $\"+x+=+sqrt%289%29+\"$
\n" ); document.write( "

\n" ); document.write( "Therefore x={3,-3}
\n" ); document.write( "

\n" ); document.write( "Hope this helped,
\n" ); document.write( "Best of luck.
