Final answer:
The discriminant of the quadratic equation -3a² + 10a - 7 = 0 is 16.
Step-by-step explanation:
The discriminant of a quadratic equation ax² + bx + c = 0 can be found using the formula:
Discriminant = b² - 4ac
In the given equation -3a² + 10a - 7 = 0, we have a = -3, b = 10, and c = -7. Substituting these values into the discriminant formula:
Discriminant = (10)² - 4(-3)(-7)
Simplifying, we get Discriminant = 100 - 84 = 16. Therefore, the discriminant of the quadratic equation -3a² + 10a - 7 = 0 is 16.
