You can put this solution on YOUR website!
You do NOT get rid of the exponent. \r

\n" ); document.write( "\n" ); document.write( "Simplify and try to factorize.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x%5E2-12x=90\"
\n" ); document.write( "\"x%5E2-12x-90=0\", factors in prime form for the constant, 3*3*2*5, and you might find in there, 6*15, something to test-try.\r

\n" ); document.write( "\n" ); document.write( "?
\n" ); document.write( "(x___6)(x____15)------no ; not work.

\n" ); document.write( "\n" ); document.write( "Factorization will basically \"not\" work.
