You can put this solution on YOUR website!
20x(3-2x)= $\"60x-40x%5E2\"$ -----> what's wrong with this? parentheses is gone
\n" ); document.write( "Continuing to solve for \"x\", becomes
\n" ); document.write( " $\"40x%5E2-60x=0\"$ ------------> working eqn
\n" ); document.write( " $\"10x%284x-6%29=0\"$
\n" ); document.write( " $\"%28cross%2810x%29%284x-6%29%29%2Fcross%2810x%29+=+cross%280%2F10x%29%2A0\"$
\n" ); document.write( " $\"4x-6=0\"$
\n" ); document.write( " $\"x=6%2F4\"$ --------> final answer for value of \"x\"
\n" ); document.write( "To check, go back to our working eqn,
\n" ); document.write( " $\"40%286%2F4%29%5E2+-+60%286%2F4%29=0\"$
\n" ); document.write( "(40)(2 1/4) - (360/4)=0
\n" ); document.write( " $\"90-90=0\"$ ---> $\"0=0\"$
