Homework Statement
∫ x^(5)-2x^(2)-1/3x^(4) dx
Homework Equations
I am familiar with the power rule and how to split the expression into three separate expressions and then simplifying. I just can't seem to sort out my algebra for this problem.
xn dx = xn+1
n + 1 + C if n is NOT= -1
x-1 dx = ln|x|+ C
The Attempt at a Solution
Here is where i become stuck...Please show me a step by step process to solving the remainder of this problem; that way i can analyze it more deeply. Please Point out any things that seem wrong,i would REALLY appreciate the help given. :) :
∫ (x^5/3x^4 -2x^2/3x^4 -1/3x^4)dx = ∫ 1/3x -2x^(-2) -1/3x^(-4)dx = ∫ (x^2/6 + 2/x +1/9x^3) + C <------- This is the part where i become flabbergasted. . .Its simple I am sure but i just cannot see it. I was thinking about multiplying the whole expression by 18x^3 but i am not sure if that is correct.
