Question

-3x^2-3x+6 find the discriminant. Show your work

Answer 1

81

Explanation:

discriminant is b² - 4ac where a is coefficient in front of x², b is coefficient in front of x and c is constant term.

a = -3, b = -3, c = 6

b² - 4ac

= (-3)² - 4(-3)(6)

= +9 - 4(-18)

= 9 + 4X18

= 9 + 72

= 81
