From a table of what?

If you have two x values that each correspond to a y value of 0, it is a simple process.

Let's say that you have two values for x, x=a and x=b, such that your table of function values has

x=a, f%28a%29=0 and

x=b, f%28b%29=0

Then you can say %28x-a%29%28x-b%29=0 and then multiply the binomials to get x%5E2-%28a%2Bb%29x%2Bab=0
