Solve by two methods, quadratic equation and factoring:
\n" ); document.write( "2x^2-x-15=0
\n" ); document.write( "

I would use the factoring method 1st, since it's easier, and you can use the solution(s) to check the solution(s) after using
\n" );
document.write( "the quadratic equation formula

\n" );
document.write( " ------- Replacing - x with - 6x + 5x

\n" );
document.write( "
\n" );
document.write( "2x + 5 = 0      OR       x - 3 = 0
