I'm sorry guys I need answers right now

lgbasallote · Answer

factoring would be easier but completing the square is safer

aravindg · Answer

yep i agree with @lgbasallote

king · Answer

But then if u were in an exam factoring would be fast and easy...

aravindg · Answer

yep always try to think !! i am sure u will then see which is the factors easily

parthkohli · Answer

I think completing the square, because I'm no able to find two numbers that multiply to get -5 and add to get -6. :/

anonymous · Answer

thanks!

lgbasallote · Answer

how about -5 and -1 @ParthKohli

anonymous · Answer

Excuse me, but this doesn't factor well. What context are we talking here?

parthkohli · Answer

-5 * -1 = 5

lgbasallote · Answer

what do you guys mean doesnt factor out well??

5x^2 - 6x - 1= 0

5x^2 - 5x - x -1 = 0

it's factorable o.O

parthkohli · Answer

$ \color{Black}{\Rightarrow 5x(x - 1) - (x + 1) = 0 }$
NOPE IT ISNT

anonymous · Answer

I mean that it does not factor over the integers. This is the usual subset of R chosen.

lgbasallote · Answer

hmm you have a point

parthkohli · Answer

As I said, $-5 \times -1= 5$

anonymous · Answer

Katie was given the incorrect answer.

And lgba was given an undeserved medal.

anonymous · Answer

Yes, but that's not his fault. Everyone is wrong from time to time. :P
