Question

Use the discriminant to describe the roots of each equation. Then select the best description. x2 - 6x + 12 = 0

Answer 1

The answer is -12
Since -12 < 0 = no solutions

Discriminant Formula: b^2 - 4ac
b^2 - 4ac > 0     2 solutions
b^2 - 4ac = 0     1 solution
b^2 - 4ac < 0     no solutions

x^2 - 6x + 12 = 0
a = 1
b = -6
c = 12

-6^2 - 4 (1) (12)
36 - 48
= -12
-12 < 0 = no solution
