Question
What is the discriminant of the quadratic equation minus, 9, x, squared, minus, 3, x, minus, 1, equals, 0−9x 2 −3x−1=0?AnswerMultiple Choice Answersminus, 45−454545minus, 27−272727
Solution
The discriminant of a quadratic equation is given by the formula D = b² - 4ac, where a, b, and c are the coefficients of the quadratic equation ax² + bx + c = 0.
In the given equation -9x² -3x -1 = 0, a = -9, b = -3, and c = -1.
Substituting these values into the formula, we get:
D = (-3)² - 4*(-9)*(-1) D = 9 - 36 D = -27
So, the discriminant of the given quadratic equation is -27.
