Question

Use the discriminant to determine the number of solutions to the quadratic equation −45d2+4d−1=0.

Answer 1

no real solutions

2 different complex solutions

Explanation:

b^2 - 4ac = 4^2 - 4(-45)(-1) = 16 - 180 = -164

Answer 2

-164 discriminates, use Quadratic Formula to get that answer. If you need number of solutions, then there’s no solutions.
