integral of (4t^2+3)^2

\int (4 t^{2} + 3)^{2} d t

\frac{16 t ^{5}}{5} + 8 t^{3} + 9 t + C

Solution steps

\int (4 t^{2} + 3)^{2} d t

Expand

(4 t^{2} + 3)^{2} : 16 t^{4} + 24 t^{2} + 9

= \int 16 t^{4} + 24 t^{2} + 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 16 t^{4} d t + \int 24 t^{2} d t + \int 9 d t

\int 16 t^{4} d t = \frac{16 t ^{5}}{5}

\int 24 t^{2} d t = 8 t^{3}

\int 9 d t = 9 t

= \frac{16 t ^{5}}{5} + 8 t^{3} + 9 t

Add a constant to the solution

= \frac{16 t ^{5}}{5} + 8 t^{3} + 9 t + C

\int (x - e^{x})^{2} d x

y^{^{'}} = 2 (x + y)^{2}

y = \frac{4}{x ^{2}}

\frac{\partial}{\partial x} (x sin (x + y))
