Evaluate:
(i) `intsqrt(x)(3-5x)\ dx`
(ii) `int((x+1)(x-2))/(sqrt(x))\ dx`

Explanation

(i) `intsqrt(x)(3-5x)\ dx`


`=int(3sqrt(x)-5x)\dx`


`=2x^(3/2)-(5x^(2))/(2)+C`


(ii) `int((x+1)(x-2))/(sqrt(x))\ dx`


`=int((x^2-x-2))/(sqrt(x))\dx`


`=int(x^(3/2)-sqrt(x)-2x^(-1/2))\dx`


`=(2x^(5/2))/(5)-(2x^(3/2))/(3)-4x^(1/2)+C`
