Question

Complex Numbers and Discriminants: Which of the following are solutions to the equation below?

4x2 - x + 5 = 0

Answer 1

use the quadratic formula determinant to determine the nature of the solutions.

Answer 2

can you tell me more about that.

Answer 3

I couldn't get the answer, please help.

Answer 4

4x^2*

Answer 5

the determinant will determine the nature and how many solutions you have...
Determinant = b^2 -4ac

if the determinant = 0, you have 1 root
if the determinant is positive, you 2 roots
if the determinant is negative, you have no real solution, 2 complex roots.

Answer 6

I still didn't get the answer.
