+sqrt2,5sqrt2 Answer by solver91311(24713) (Show Source):
If is a root of a polynomial equation, then must be a factor of the polynomial. Since a quadratic equation has two roots, if you are given both of them, you can immediately derive the two factors of the quadratic trinomial:
Just multiply the two binomials using FOIL. Note: Not all of the coefficients of your final answer will be rational.
