Question

Factoring... again... (1 of 11)

Answer 1

\[12x^2-5x-3\]
a=12 b=-5 c=-3 ac=-36
(1)(36) (2)(18) (3)(12) (4)(9) (6)(6)

Answer 2

Looks good so far :)

Answer 3

\[-9+4=-5/]
\[-9*4=-36\]

Answer 4

Good

Answer 5

\[12x^2-(9+4)x-3\]

Answer 6

\[12x^2-9x+4x-3\]

Answer 7

\[3x(4x-3)+1(4x-3)\]

Answer 8

Looks really great so far!!

Answer 9

Oh but wait ...

Answer 10

Yes?

Answer 11

\(12x^2-(9+4)x-3\)

Start with this step. This step is correct. Then continue from here but remember to DISTRIBUTE the negative.

Answer 12

\[12x^2-9x-4x-3\]

Answer 13

Very good. Now you may continue.

Answer 14

\[(12x^2-9x)-(4x-3)\]

Answer 15

\[3x(4x-3)-1(4x-3)\]

Answer 16

Ah, I see what you did now. Should have caught that one. You keep forgetting to properly replace the five with an equivalent expression. 5 = 9 - 4 not 9 + 4

Answer 17

Because 9 + 4 = 13 which is clearly not 5 so you have to be careful when replacing

Answer 18

\(12x^2-(9-4)x-3\) This is correct

Answer 19

What?

Answer 20

9 - 4 =
9 + 4 =

Answer that above then we can continue

Answer 21

5
13

Answer 22

Okay, do you understand now which expression is the correct expression to replace with 5?

Answer 23

9-4

Answer 24

Very good. So now, can you continue from here?
\(12x^2-(9-4)x-3\)

Answer 25

\[12x^2-9x-4x-3\]

Answer 26

Well, then you'd have the same expression as before. When you distribute the negative the signs within parenthesis flip flop.

Answer 27

The positive number becomes negative. The negative number becomes positive.

Answer 28

\[12x^2-9x+4x-3\]

Answer 29

There we go. Now you may finish finally.

Answer 30

Ugh... I feel dumb.. I’m still getting \[3x(4x-3)1(4x-3)\]

Answer 31

There is a plus missing. Otherwise it is correct.

Answer 33

Yes, very good. Now factor out the binomial common to each factorization.

Answer 34

\[(3x+1)(4x-3)\]

Answer 35

I need to go.

Answer 36

Okay, well keep practicing. You're making huge progress. Never give up!
