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

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

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

Solution steps

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

Expand

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

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

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 x^{4} d x + \int 24 x^{2} d x + \int 9 d x

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

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

\int 9 d x = 9 x

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

Add a constant to the solution

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

x^{2} - x, 2 x - 2 x^{2}

x \to 4 lim (\frac{1}{x + 2})

e^{x} - 6 x^{5}

\int (3 x^{2} - 4)^{2} x^{3} d x

\frac{\partial}{\partial y} (e^{x})
