Question
What is the discriminant of the quadratic equation minus, 6, x, squared, plus, 9, x, minus, 7, equals, 0−6x 2 +9x−7=0?AnswerMultiple Choice Answers249249minus, 249−249minus, 87−878787
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 -6x² + 9x - 7 = 0, a = -6, b = 9, and c = -7.
Substituting these values into the formula, we get:
D = (9)² - 4*(-6)*(-7) D = 81 - 168 D = -87
So, the discriminant of the given quadratic equation is -87.
