Answer:
8x + 2 and 4x - 6
Step-by-step explanation:
(f + g)(x)
= f(x + g(x)
= 6x - 2 + 2x + 4 ← collect like terms
= 8x + 2
(b)
(f - g)(x)
= f(x) - g(x)
= 6x - 2 - (2x + 4) ← distribute parenthesis by - 1
= 6x - 2 - 2x - 4 ← collect like terms
= 4x - 6
I think it’s C from my experience

Answer:
Step-by-step explanation:
3x^4 - 9x^2 - 12 = 0
x^4 - 3x^2 - 4 = 0
x^2 = [3 ± √(3^2-4(1)(-4))]/[2(1)] = [3 ± 5]/2 = 4,-1
f(x) = 3(x^2-4)(x^2+1) = 3(x+2)(x-2)(x^2+1)
