Question

How would you go about solving this quadratic equation? I'm having trouble with the process.
2x^2+9x-5=0

Answer 1

2 ways you can solve it

1. factoring it out and solving for x

2. using the quadratic equation

Answer 2

How do I know if I can factor it?

Answer 3

experience, mainly,
if you look at enough of them, you can determine whether or not its factorable

either that, or you can look at the determinant of the equation

Answer 4

"Determinant?" - do you mean 'discriminant' @completeidiot ?

Answer 5

yes i meant discriminant, i was close

Answer 6

Yeah, I mix those two up sometimes too.

Answer 7

Okay, thanks! I will probably just factor it.
I will be back, I have to leave. I'll check back later.

Answer 8

*hint: this polynomial is factorable.
