integral of ((6-2x)/(sqrt(8-4x-4x^2)))

\int (\frac{6 - 2 x}{8 - 4 x - 4 x ^{2}}) d x

\frac{7}{2} arcsin (\frac{2}{3} x + \frac{1}{3}) + - x^{2} - x + 2 + C

Solution steps

\int \frac{6 - 2 x}{8 - 4 x - 4 x ^{2}} d x

Expand

\frac{6 - 2 x}{8 - 4 x - 4 x ^{2}} : \frac{3}{2 - x - x ^{2}} - \frac{x}{2 - x - x ^{2}}

= \int \frac{3}{2 - x - x ^{2}} - \frac{x}{2 - x - x ^{2}} 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 \frac{3}{2 - x - x ^{2}} d x - \int \frac{x}{2 - x - x ^{2}} d x

\int \frac{3}{2 - x - x ^{2}} d x = 3 arcsin (\frac{2}{3} x + \frac{1}{3})

\int \frac{x}{2 - x - x ^{2}} d x = - - x^{2} - x + 2 - \frac{1}{2} arcsin (\frac{2}{3} x + \frac{1}{3})

= 3 arcsin (\frac{2}{3} x + \frac{1}{3}) - (- - x^{2} - x + 2 - \frac{1}{2} arcsin (\frac{2}{3} x + \frac{1}{3}))

Simplify

3 arcsin (\frac{2}{3} x + \frac{1}{3}) - (- - x^{2} - x + 2 - \frac{1}{2} arcsin (\frac{2}{3} x + \frac{1}{3})) : \frac{7}{2} arcsin (\frac{2}{3} x + \frac{1}{3}) + - x^{2} - x + 2

= \frac{7}{2} arcsin (\frac{2}{3} x + \frac{1}{3}) + - x^{2} - x + 2

Add a constant to the solution

= \frac{7}{2} arcsin (\frac{2}{3} x + \frac{1}{3}) + - x^{2} - x + 2 + C

\frac{d}{d x} (\frac{7}{x ^{4} + 3})

\frac{\partial}{\partial x} ((x - 1)^{2} + 8 (y - 1)^{2})

x \to \frac{π}{4} lim ((tan (x))^{t a n (2 x)})

x \to 5 + lim (ln (x^{2} - 25))

y = x 16 - x^{2}
