integral of 2t+9

Solution

\int 2 t + 9 d t

Solution

t^{2} + 9 t + C

Solution steps

\int 2 t + 9 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 t d t + \int 9 d t

\int 2 t d t = t^{2}

\int 9 d t = 9 t

= t^{2} + 9 t

Add a constant to the solution

= t^{2} + 9 t + C
