DISCOVER ■ Prove: Relationship Between Roots and
Coefficients The Quadratic Formula gives us the roots of a
quadratic equation from its coefficients. We can also obtain
the coefficients from the roots. For example, find the roots
of the equation x2  9x  20  0 and show that the product
of the roots is the constant term 20 and the sum of the roots is
9, the negative of the coefficient of x. Show that the same
