## lovelymultani ∫(2x+1)⋅(x−3) /x dx one year ago one year ago

1. dumbcow

multiply the expression out.... then just use the power rule

2. lovelymultani

the X is the denominator, does that change the process?

3. dumbcow

haha not really just treat it as x^-1

4. dumbcow

so (2x^2 -5x -3)*x^-1 = 2x -5 -3x^-1 still use power rule to integrate

5. lovelymultani

Lol im forgetting all the rules. Ok to get rid of the x's u divided by x?

6. Callisto

$\int x^n dx = \frac{1}{n+1}x^{n+1}+c$

7. Callisto

You also need this: $\int \frac{1}{x}dx = \ln x +C$
