You can put this solution on YOUR website!
These problems cannot be solved without irrational answers. If you calculate, $\"b%5E2+-+4ac\"$ from the quadratic formula for each of these problems, you do NOT get perfect squares. Therefore, the exact values of these answers cannot be expressed without square roots. \r

\n" ); document.write( "\n" ); document.write( "Another way of saying this is that since $\"b%5E2+-+4ac\"$ is NOT a perfect square, that means that the equations CANNOT be factored! Therefore the answers cannot be expressed exactly without radicals.\r
