Medal+Fan

If f(x) = 3x + 5 and g(x) = 2x - 9, find f(x) - g(x).
A. 5x + 4
B. x - 4
C. x + 14
D. 5x - 4

I choose answer B but i got it wrong

Answer 1

f(x) = 3x +5 ----------(1)
g(x) = 2x - 9 ----------(2)

(1) -(2)

f(x) -g(x) = 3x + 5 - [ 2x -9 ]
now what you ave to do is ... solve this part
3x + 5 - [ 2x - 9]
first remove the brackets.
add and subtract the like terms
thats all

can u do that ?
