# Math Help - Integral

1. ## Integral

I tried integrating this but I don't get the right answer. My graphing calculator shows the answer all over 15 but I don't have the numerator right.

integral (x^2+ 2x)/(2squarerootx) dx

I tried taking out the 1/2 then integrating by putting the squarerootx on the numerator but it didn't work. Should I use another integration method?

it is simply using the power rule. simplify the fraction by dividing $2 \sqrt x$ into each term in the numerator. recall for fractions $\frac {A + B}C = \frac AC + \frac BC$

can you finish now?
