Factor a number, variable, or expression out of the polynomial shown below. 7x - 21

7(x - 3)

Hope this helps! 🙂

Both 3x and 9 are a multiple of 3, so we can factor out a 3:

3x + 9 = 3 (x + 3)

X(5x+9)

x appears in both terms, so you can take it out

This I quiet easy all u do is what I show u above I hope this help because I want to show help others

20x^3 + 15xfactoring out 5x

5x(4x^2 + 3)

[tex]15x^{3}+20x=5x(3x^{2}+4)[/tex]

==================================

"Associate with people who are likely to improve you."

B is the answer cause when u put them all in that what i got

Factor out the (4x-5), which is the GCF to go from

x(4x-5) + 9(4x-5)

to

(4x-5)(x+9)

Note: (4x-5)(x+9) is the same as (x+9)(4x-5). The order of the factors does not matter. You can multiply in any order.

Therefore, the final answer is choice B

15x^{3}+20x=5x(3x^{2}+4) GOODLUCK

5x(3x^2 + 4)

Hope this helps! 🙂
