Answer:

2x² + 7x + 2

Explanation:

f(x) = 3x² + 5

g(x) = 4x - 2

h(x) = x² - 3x + 1

f(x) + g(x) — h(x) =

(3x² + 5) + (4x - 2) - (x² - 3x + 1) = ==> plugin the values of f(x), g(x), and h(x)

3x² + 5 + 4x - 2 - (x² - 3x + 1) =

3x² + 5 + 4x - 2 - x² + 3x - 1 = ==> distribute the negative sign to x², -3x, 1

x² ==> -x², -3x ==> 3x, 1 ==> -1

3x² - x² + 4x + 3x + 5 - 2 - 1 = ==> combine like terms

2x² + 7x + 2 = ==> simplify
