Answer:

See Explanation

Step-by-step explanation:

Details are not clear. So, I will use the following

[tex]f(x) = x^3 - 4x + 2[/tex]

[tex]g(x) = x - 2[/tex]

Required

Find f(x) - g(x)

This is calculated as:

[tex]f(x) - g(x) = x^3 - 4x + 2 - (x - 2)[/tex]

Open  bracket

[tex]f(x) - g(x) = x^3 - 4x + 2 - x + 2[/tex]

Collect like terms

[tex]f(x) - g(x) = x^3 - 4x - x + 2 + 2[/tex]

[tex]f(x) - g(x) = x^3 - 5x + 4[/tex]
