Question

let f(x) = 4x -5 and g(x) = 6x - 3. find f(x) - g(x).

Answer 1

f(x) = -4x - 5
g(x) = -6x - 3

-4x - 5
- -6x - 3

-4x - 5
6x + 3
2x - 2

Answer 2

Answer: f(x) - g(x) = -2x -2.

Step-by-step explanation:

It is given that f(x) = 4x - 5 and g(x) = 6x - 3. Calculate the difference between f(x) and g(x) as follows.

                 f(x) - g(x)  

            = 4x - 5 - 1 × (6x - 3)    → Using distributive property A × (B - C)      

           = 4x - 5 - 6x + 3

           = -2x -2

Thus, f(x) - g(x) = -2x -2.
