Roots and the Discriminant
DiscriminantThe expression under the radical sign, b 2 - 4ac, in the Quadratic Formula is called the discriminant.DiscriminantType and Number of Roots
b 2 - 4ac > 0 and a perfect square 2 rational roots b 2 - 4ac > 0, but not a perfect square2 irrational roots b 2 - 4ac = 01 rational root b 2 - 4ac < 02 complex roots Find the value of the discriminant for each equation. Then describe the number and type of roots for the equation. a. 2 x 2 + 5x + 3The discriminant is
b 2 - 4ac = 5 2 - 4(2) (3) or 1.The discriminant is a perfect square, so
the equation has 2 rational roots.b. 3x 2 - 2x + 5The discriminant is
b 2 - 4ac = (-2) 2 - 4(3) (5) or -56.The discriminant is negative, so the
equation has 2 complex roots.Exercises
