Question

What multiplies to get -6 and adds up to 3

Answer 1

factor -6
and 3

Answer 2

what two number you should multiply to get -6 ?
and what two number you should multiply to get 3 ??
what number are divisible by 3?

Answer 3

so list the factors of 6. Is the first thing Nnesha wants you to do.

Answer 4

@snwjwk
WELCOME TO OS :D

Answer 5

can you do that @snwjwk ?

Answer 6

-6*1=-6
2*-3=-6
Adds up to 3
2+1=3

Answer 7

ah, but you have 2+-3 that =-1

Answer 8

keep going with the factoring

Answer 9

okay nice -6 times 1 = -6
2 times -3 = -6
which pair of two number give u the positive 3 ??

Answer 10

maybe mess with which values are negative and which are positive

Answer 11

^yeah play with signs

Answer 12

I'm stuck and clue less

Answer 13

There isn't actually an answer

Answer 14

do you have an equation ?

Answer 15

it's a trick question :/ but in general this is your algorithm: list the factors of |-6| until you would repeat a number.\[1*6\\2*3\]
Now, if your other number is positive, the smaller numbers must be negative. If the number is negative, the big numbers must win and be negative. So here we have negative little numbers. \[-1*6\\-2*3\] So you add those and are like, none of those work! so we cannot get a solution to this question

Answer 16

Yeah identify any cvs lies for which expression is undefined
X^2-x-2
----------
3x-6

Answer 17

Values

Answer 18

oh, use the quadratic formula for that

Answer 19

don't try and factor it normally, that only works if it factors into integers

Answer 20

So it would be no solution

Answer 21

no, you just use the quadratic formula to factor it

Answer 22

do you know it?

Answer 23

No

Answer 24

ohohoohohoohohohohohoh

Answer 25

wait a second.

Answer 26

K

Answer 27

do you have this? \[\frac{x^2-x-2}{3x-6}\]

Answer 28

Yes

Answer 29

ohhkkk, so that just means the denominator =0

Answer 30

we cannot divide by zero right?

Answer 31

so if it does, we go crazy and can't have that

Answer 32

It doesn't say

Answer 33

^that is fact

Answer 34

so set the denominator =0 and solve for x, can you give that a try?

Answer 35

I don't have to factor the top
-2 *-1=-2
-2+-1=-1

Answer 36

nope

Answer 37

Okay

Answer 38

it's only when the denominator equals zero that you have a problem

Answer 39

Okay

Answer 40

What times -25 and adds up 1
Wouldn't that just factor 5?

Answer 41

nah just solve 3x-6=0

Answer 42

what's x =? That's your answer
