DETAILED EXPLANATION

\n" ); document.write( "
Look at \"highlight_red%28+x%5E2-3%2Ax-4+%29=0\".
Equation \"highlight_red%28+x%5E2-3%2Ax-4=0+%29\" is a quadratic equation: x^2-3*x-4 =0, and has solutions 4,-1
It becomes \"highlight_green%28+0+%29=0\".
Result: \"0=0\"
\n" ); document.write( "This is an equation! Solutions: x=4,x=-1.
