You can put this solution on YOUR website!
Your original equation was:
\n" ); document.write( " $\"%28x%2A-3x%29%2B8=0\"$
\n" ); document.write( "suppose * = 2. then we have a quadratic of the form
\n" ); document.write( " $\"%28x2-3x%29%2B8=0\"$
\n" ); document.write( "which can easily be solved using the quadratic formula as
\n" ); document.write( " $\"x+=+%283+%2B-+sqrt%28+9-4%2A1%2A8+%29%29%2F%282%2A1%29+\"$
\n" ); document.write( "which is simplified as
\n" ); document.write( " $\"x+=+%283+%2B-+sqrt%28-23%29%29%2F2+\"$
\n" ); document.write( "From here you have one of two ways to go.
\n" ); document.write( " (1) if you have never been shown imaginary numbers, then say no solution.
\n" ); document.write( "(2) If you have been shown imaginary numbers, then say
\n" ); document.write( " $\"%283+%2B+isqrt%2823%29%29%2F2\"$ , $\"%283+-+isqrt%2823%29%29%2F2\"$ \n" ); document.write( "

\n" );
