Answer 1

what would go into twelve times that would add up to -9

Answer 2

but it says factored completely

Answer 3

(3x-3)(x+4)

Answer 4

that isnt a choice :(

Answer 5

we're not done

Answer 6

what?

Answer 7

3x^2-12x+3x-12

Answer 8

(3x^2-12x) (3x-12)

Answer 9

What is 3x^2-9x-12 when factored completely?

3(x^2 -3x -4)
3(x-4)(x+1)

Answer 10

each term has a coefficicient that is a multiple of 3

so start by taking 3 as a common factor

\[3(x^2 + 3x - 4)\]

now just factorise the quadratic

Answer 11

Its 3(x-4)(x+1) thanks my_lyfe

Answer 12

no problem and your welcome!

Answer 13

thats not answer

Answer 14

the correct answer is 3(x + 4)(x -1)

but its just a simple error

Answer 15

Answer 16

Factor my answer and you will get your problem
