Question

Help me simplify this please:

Answer 1

\[ \huge f(x)= \frac{ 2(x+h)^3-(2)2 }{ h }\]

Answer 2

\[\huge f(x)= \frac{ [2(2^3+3(2^2h)+3(2h^2)+h^3]-4 }{ h}\]

Answer 3

now evaluate the small brackets

Answer 4

question: in original problem , yours is (x +h)^3 but when expanding, it turns to (2+h)^3??

Answer 5

@Loser66 it was a typo in the original
