Find all zeros of P(x)= x^2+3x^2-4x-12\r
\n" ); document.write( "\n" ); document.write( "We need to solve:\r
\n" ); document.write( "\n" ); document.write( "x^2 + 3x^2 - 4x - 12 = 0\r
\n" ); document.write( "\n" ); document.write( "Collecting terms we have;
\n" ); document.write( "4x^2 - 4x - 12 = 0\r
\n" ); document.write( "\n" ); document.write( "Divide both sides by 4:\r
\n" ); document.write( "\n" ); document.write( "x^2 - x - 3 = 0\r
\n" ); document.write( "\n" ); document.write( "Use the quadratic formula where a=1, b= -1, c= -3 to solve for x.
\n" ); document.write( "
\n" );
