The factors of 9 are 1, 3 and 9.
The factors of 12 are 1, 2, 3, 4, 6 and 12.
The factor of a and a^2 is just "a."

For coefficients, the common factors of 9 and 12 are 1 and 3 only. But the greatest common factor is 3.
For variables, the greatest factor is just also "a."

Multiplying these two factors, we get the answer: 3a

PLEASE HELP WITH EXPLANATION <br><br> F(x) = 3 - x; g(x) = -2x <br><br> find f(g(2))
ioda

Given,

f(x) = 3 - x

and

g(x) = -2x

Now,

g(2) =  - 2(2) =  - 4

f(g(2)) = 3 - ( - 4) = 3 + 4 = 7
