If A = -3n + 2 and B = 5n - 7, what is the value of A - B, in simplest form?

-8n+9

Step-by-step explanation:

To solve this you set up your equation and then combine like terms. We know that A=-3n+2 and B=5n-7 and so when we subtract A and B we have

-3n+2-(5n-7)

Combine like terms and you get -8n+9

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
