Answer:

see explanation

Explanation:

(a)

f(x) + g(x)

= - 2
x^(4) - 7x² - 6 - 2x³ + 6x

= - 2
x^(4) - 2x³ - 7x² + 6x - 6 ← in standard form

(b)

f(x) - g(x)

= - 2
x^(4) - 7x² - 6 - (- 2x³ + 6x) ← distribute parenthesis by - 1

= - 2
x^(4) - 7x² - 6 + 2x³ - 6x

= - 2
x^(4) + 2x³ - 7x² - 6x - 6 ← in standard form
