Question

use the discriminant to determine the nature of the roots of 5x^2 - 5x -60=0

Answer 1

The discriminant: \(\Large b^2-4ac\)
Use the standard form: \(\Large Ax^2+Bx+C=0\)

Answer 2

Im decent at solving then but for some reason its hard for me to find how many real roots it has or two or three distinct real roots

Answer 3

A square function can only have two roots, real and unreal I think.

Answer 4

Either two real solutions, two imaginary solutions or none.
