elixir [45]

Answer:

(f-g)(x)  =  - 3 x² + 3 x -6

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given function f(x) = x² + x - 5

                      g(x) = 4 x² - 2 x + 1

(f-g)(x)   =  f(x) - g(x)

            =  x² + x - 5 - (4 x² - 2 x + 1)

            = x² - 4 x² + x + 2 x - 5 -1

            =  - 3 x² + 3 x -6

(f-g)(x)  =  - 3 x² + 3 x -6
