F(x) = 2x² - 2x + 7
g(x) = x² + 9x - 6
f(x) - g(x) = 2x² - 2x + 7 - (x² + 9x - 6)
= 2x² - 2x + 7 - x² - 9x + 6
= 2x² - x² - 2x - 9x + 7 + 6
= x² - 11x + 13
The 1st option.
Answer:
<h3>
Commutative property </h3>
Step-by-step explanation:
The "Commutative Laws" say: when we add we can swap numbers over and still get the same answer.
