You can put this solution on YOUR website!
P(x) = x^3 − 3x^2 − 28x
\n" ); document.write( "Factor out x
\n" ); document.write( "x(x^2 - 3x - 28) = 0
\n" ); document.write( "factor the quadratic
\n" ); document.write( "x(x-7)(x+4) = 0
\n" ); document.write( "Three zeros
\n" ); document.write( "x = 0, 7, -4
\n" ); document.write( " \n" ); document.write( "

\n" );
