try using the quadratic formula

alright. let me try this out.

ok take your time

how would it work considering the first term is cubed, not squared?

how would that help?
i don't understand.

i know it simplifies to 4y3 - 37y/12 + 2.99.

do you have an easier way of explaining this?

let me think...

lol.. wow thats neat work... @pathosdebater

Is the problem 4x3 + 5x2 – x + 2 or 4*3 + 5*2 – x + 2? (Just making sure)

It's exponential, yeah. 4x^3 + 5x^2 - x + 2.

What? Oh... I didn't know that.
I thought it was 4x*3 + 5x*2 - x+2

One second

Sorry for the confusion.

This is so strange. I keep getting irrational answers.
Is there anything wrong in my calculations which could be causing this?

What textbook is it?

Hmm... well there are definitely only 3 roots, so that narrows it down to C and D.

Thanks for the help though, I'm just going to guess. I appreciate the effort.

I got it! It is definitely C

That was my initial guess, but can you explain how?

2 is not a complex root

Let me see if I can try and explain...

its got to have two complex roots ..if not zero

have u done complex numbers @pathosdebater

Only briefly. I'm not a wizard at them... yet
