integral of ((2t^2+tsqrt(t)-1))/(t^2)

\int \frac{( 2 t ^{2} + t t - 1 )}{t ^{2}} d t

2 t + 2 t + \frac{1}{t} + C

Solution steps

\int \frac{2 t ^{2} + t t - 1}{t ^{2}} d t

Expand

\frac{2 t ^{2} + t t - 1}{t ^{2}} : 2 + \frac{1}{t} - \frac{1}{t ^{2}}

= \int 2 + \frac{1}{t} - \frac{1}{t ^{2}} d t

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int 2 d t + \int \frac{1}{t} d t - \int \frac{1}{t ^{2}} d t

\int 2 d t = 2 t

\int \frac{1}{t} d t = 2 t

\int \frac{1}{t ^{2}} d t = - \frac{1}{t}

= 2 t + 2 t - (- \frac{1}{t})

Simplify

= 2 t + 2 t + \frac{1}{t}

Add a constant to the solution

= 2 t + 2 t + \frac{1}{t} + C
