(x + 4)(x − 5)
(x + 5)(x − 4)
(x − 10)(x + 2)

I don get what the answer is supposed to be if they are both correct e.e

Answer 1

Answer 2

Ik that you have to get it in two ()

Answer 3

Alright so a polynomial function has y=ax^2+bx+c

Answer 4

Okay

Answer 5

The C value determines the factors of the equation. What multiplied by what can equal 20?

Answer 6

Well it has to be -20 cause it has -20 at the end

Answer 15

I very much am.

Answer 16

.........

Answer 17

Kay I give up @dude you work on this patient right here

Answer 18

Those are the right multiples, since we have a -20 we need a negative and a positive number
(x+number) and (x-number)

Which of these numbers can add up to 8 with 1 positive number and 1 negative number?

Answer 19

-2,10

Answer 20

Can you just go...

Answer 21

I was going to compliment dude but my hand was tweaking.

Answer 22

Not quite, adding -2 and 10 would give you +8, not -8

Answer 23

so then it would be the opposite

Answer 24

Right

Answer 25

So Answer would be C

Answer 26

Correct

Not sure how it appeared like that, but it's not actually like that, sometimes it can fall out of sync, and I haven't figured out the exact cause for it @dude

It's quite rare though
