Answer:

(x + 2) is a factor of f(x)

Step-by-step explanation:

Using the remainder theorem to divide f(x) by (x - h)

Evaluate f(h) and if equal to 0 then (x - h) is a factor

f(- 3) = (- 3)³ - 7(- 3)² + 36 = - 27 - 63 + 36 ≠ 0

f(- 2) = (- 2)³ - 7(- 2)² + 36 = - 8 - 28 + 36 = 0

f(- 6) = (- 6)³ - 7(- 6)² + 36 = - 216 - 252 + 36 ≠ 0

f(2) = 2³ - 7(2)² + 36 = 8 - 28 + 36 = 16 ≠ 0

Hence (x + 2) is a factor of f(x)
