Answer:
f(x) = x^2 + 2x - 3 and g(x) = x^2 - 9
(f/g)(x) = (x^2+ 2x -3) / (x^2 - 9)
(f/g)(x) = (x +3 )(x - 1) / (x + 3)(x - 3)
(f/g)(x) = (x - 1) / (x - 3)
So
(f/g)(4) = (4 - 1)/(4 -3)
(f/g)(4) =3/1
(f/g)(4) = 3
(f+g)(x) = x^2+ 2x - 3 + x^2 - 9
(f+g)(x) = 2x^2 + 2x - 12
(f+g)(x) = 2(4)^2 + 2(4) - 12
(f+g)(4) = 32 + 8 - 12
(f+g)(4) = 28
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Given
(x - 5)³ = (x - 5)(x - 5)(x - 5)
Expand (x - 5)(x - 5) using FOIL then multiply the result by (x - 5)
(x - 5)(x - 5)
= x² - 5x - 5x + 25 = x² - 10x + 25, then
(x - 5)(x² - 10x + 25)
= x(x² - 10x + 25) - 5(x² - 10x + 25)
= x³ - 10x² + 25x - 5x² + 50x - 125 ← collect like terms
= x³ - 15x² + 75x - 125 → D
