\"3x%5E2+-+18x+%2B+24+=+18\"
\n" ); document.write( "subtract 24 from both sides
\n" ); document.write( "\"3x%5E2+-+18x+=+-6\"
\n" ); document.write( "divide both sides by 3
\n" ); document.write( "\"x%5E2+-+6x+=+-2\"
\n" ); document.write( "take 1/2 of the coeffecient of x, then square it, then add it to both sides
\n" ); document.write( "\"x%5E2+-+6x+%2B+9+=+-2+%2B+9\"
\n" ); document.write( "\"%28x+-+3%29%5E2+=+7\"
\n" ); document.write( "\"x+-+3+=+0+%2B-sqrt%287%29\"
\n" ); document.write( "-------------------------
\n" ); document.write( "\"x+-+3+=+sqrt%287%29\"
\n" ); document.write( "\"x+=+3+%2B+sqrt%287%29\" answer
\n" ); document.write( "-------------------------
\n" ); document.write( "\"x+-+3+=+-sqrt%287%29\"
\n" ); document.write( "\"x+=+3+-+sqrt%287%29\" answer
