Factor the expression: 12x^2-16x

4x(3x-4)

To check and see if you are right you would factor over and see if you got back the equation.

4x(3x)=12x^2 because the ^2 comes from the 2 x's.

4x(-4)=-16x

so you get your equation

4x(3x-4)

Step-by-step explanation:

Basically, to factor something, you must take the GCF of both terms

In this case, you can factor out a number and a variable!

The greatest common factor between -16x and 12x^2 is 4x

So you extract that and put it outside the parenthesis.

it should look like this once its fully factored!

4x(3x-4)

80%

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
