%28x%5E3-19x-30%29%2F%28x%2B3%29
=%28x%5E3-9x-10x-30%29%2F%28x%2B3%29
=%28x%28x%5E2-9%29-10%28x%2B3%29%29%2F%28x%2B3%29
=%28x%28x%5E2-3%5E2%29-10%28x%2B3%29%29%2F%28x%2B3%29
=%28x%28x-3%29%28x%2B3%29-10%28x%2B3%29%29%2F%28x%2B3%29
=%28x%2B3%29%28x%28x-3%29-10%29%2F%28x%2B3%29
=cross%28%28x%2B3%29%29%28x%28x-3%29-10%29%2Fcross%28%28x%2B3%29%29
=x%28x-3%29-10
=x%5E2-3x-10........replace -3x with 2x-5x
=x%5E2%2B2x-5x-10
=x%28x%2B2%29-5%28x%2B2%29
=%28x%2B2%29%28x-5%29%29
