integral of (4x^2)/(x^2)

\int \frac{4 x ^{2}}{x ^{2}} d x

4 x + C

Solution steps

\int \frac{4 x ^{2}}{x ^{2}} d x

Cancel the common factor:

x^{2}

= \int 4 d x

Integral of a constant:

\int a d x = a x

= 4 x

Add a constant to the solution

= 4 x + C

\int \frac{2 x ^{2} + 9 x + 2}{( x ^{2} + 1 ) ^{2}} d x

\frac{d}{d x} (\frac{y ^{2} - x ^{2}}{( x ^{2} + y ^{2} ) ^{2}})

\int_{0}^{1} tan (\frac{π}{4} x) d x

\int sin^{2} (x) - cos^{2} (x) d x

e^{x} \frac{d y}{d x} + 2 e^{x} y = 1
