Answer :
Answer:
(f - g)(x) = 5x² - x - 4
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 4x² - 6x - 1 - (- x² - 5x + 3) ← distribute parenthesis by - 1
= 4x² - 6x - 1 + x² + 5x - 3 ← collect like terms
= 5x² - x - 4
Answer:
(f - g)(x) = 5x² - x - 4
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 4x² - 6x - 1 - (- x² - 5x + 3) ← distribute parenthesis by - 1
= 4x² - 6x - 1 + x² + 5x - 3 ← collect like terms
= 5x² - x - 4
