You can put this solution on YOUR website!
the roots are the values of x that make the value of the function zero
\n" ); document.write( "__ the points on the graph of the function where it crosses the x-axis\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "0=x^2+4x-45\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "factoring __ 0=(x+9)(x-5)
\n" ); document.write( "
\n" );
