You can put this solution on YOUR website!
the x-intercepts are when y equals zero (also called roots)\r

\n" ); document.write( "\n" ); document.write( "0 = 3x^2 + 18x + 15\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "dividing by 3 ___ 0 = x^2 + 6x + 5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "factoring ___ 0 = (x + 5)(x + 1)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x + 5 = 0 ___ x = -5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x + 1 = 0 ___ x = -1
\n" ); document.write( "
