Let f(x) = 4x3 – 5x2 – 8 and
g(x) = -2x3 – 6x² – 9x-5
Find (f-g)(x).

(f - g)(x)

Step-by-step explanation:

6x3 + x2 + 9x - 3

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
