to find a cubic equation with roots x%5B1%5D=6,x%5B2%5D=-1, and x%5B3%5D=3 use zero product formula:
f%28x%29=%28x-x%5B1%5D%29%28x-x%5B2%5D%29%28x-x%5B3%5D%29

f%28x%29=%28x-6%29%28x-%28-1%29%29%28x-3%29
f%28x%29=%28x-6%29%28x%2B1%29%28x-3%29
f%28x%29=%28x%5E2-5x-6%29%28x-3%29
f%28x%29=x%5E3-8x%5E2%2B9x%2B18
