Question
What is the discriminant of the quadratic equation minus, x, squared, plus, 7, x, minus, 1, equals, 0−x 2 +7x−1=0?AnswerMultiple Choice Answersminus, 45−45minus, 53−5353534545
Solution
The discriminant of a quadratic equation is given by the formula b² - 4ac, where a, b, and c are the coefficients of the quadratic equation ax² + bx + c = 0.
In the given equation -x² + 7x - 1 = 0, a = -1, b = 7, and c = -1.
Substituting these values into the formula, we get:
Discriminant = b² - 4ac = (7)² - 4*(-1)*(-1) = 49 - 4 = 45
So, the discriminant of the given quadratic equation is 45.
