If a polynomial equation in has a root , then the polynomial has a factor of .

Since it is a quadratic equation you seek and we know that all quadratic equations have two roots, -3.5 and 2.2 represent all of the roots for the desired equation. Therefore the equation can be found by multiplying the two factors:



Now all you have to do is FOIL it.
