This I quiet easy all u do is what I show u above I hope this help because I want to show help others [tex]Factor a number, variable, or expression out of the polynomial shown below. 7x - 21[/tex]Reply

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

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

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! 🙂
