Answer:
The answer to your question is: the answer is the second one
Step-by-step explanation:
Data
F(x) = 2x - 1
G(x) = 3x + 2
H(x) = x²
Find H(x + a) - H(x)
H(x + a) = (x+a)² substitution
= x² + 2xa + a² expanding
H(x + a) - H(x) = x² + 2xa + a² - x² simplifying
H(x + a) - H(x) = 2xa + a² or a² + 2ax
