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

anonymous · Answer

2 ways you can solve it

1. factoring it out and solving for x

2. using the quadratic equation

anonymous · Answer

How do I know if I can factor it?

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

yes i meant discriminant, i was close

anonymous · Answer

Yeah, I mix those two up sometimes too.

anonymous · Answer

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

anonymous · Answer

*hint: this polynomial is factorable.
