The discriminant D of a quadratic is equal to b 2 − 4 a c , where the quadratic is equal to a x 2 + b x + c .
Here, a = 3 , b = − 5 , and c = 3 . Plugging in values, D = ( − 5 ) 2 − 4 × 3 × 3 = 2 5 − 3 6 = − 1 1 < 0 . If the discriminant of a quadratic is less than 0 , then the quadratic has 2 distinct non-real roots
