Question

what times what eqauls -9 but still adds up to -10?

Answer 1

do you want to solve this like a riddle, or are you doing "2 equations, 2 unknowns"?

Answer 2

or are you factoring?

Answer 3

factoring

Answer 4

factoring trinomials

Answer 5

u gonna answer?

Answer 6

hmm..

(-9) x (1) = -9
But (9) + (1) = -8

If the product was supposed to be postive 9, then you could multiply (-9) x (-1) = 9, and the two factors would add to equal -10.

Answer 7

@JakeV8 best way is to use algebra....

Answer 8

that was my first thought too.

Answer 9

no one said the factors had to be integers after all

Answer 10

true. I don't know if the apparent 2 equations given as this problem are actually the problem or part of a different problem.

But either way, yes, you are right about the factors.

Answer 11

Go for it... my brain still hurts from earlier :(

Answer 12

@lgbasallote any chance you want to help on this one? I may only be online another minute or 2.

Answer 13

ill help if you want

Answer 14

sure, @JamesWolf is up to the challenge!! Go for it!

Answer 15

well cant i just say "not factor-able"

Answer 16

you have to factor? i was going to use quadratic equation

Answer 17

@JakeV8 you say that and yet you just switched to another question hmmm

Answer 18

was an easier question... see you later... I'm off

Answer 19

anyone?

Answer 20

working on it

hmmm you just turned this question into something more complex than it should be

Answer 22

i dont understand? its the same question.

Answer 23

yes exactly. your solution is overcomplicating a simple question...

Answer 24

\[ n = 5 \pm \sqrt{34}\]
