expand 8sqrt((x+2)^2+y^2)

expand

8 (x + 2)^{2} + y^{2}

8 x^{2} + 4 x + 4 + y^{2}

Solution steps

8 (x + 2)^{2} + y^{2}

(x + 2)^{2} + y^{2} = x^{2} + 4 x + 4 + y^{2}

= 8 x^{2} + 4 x + y^{2} + 4

f (\frac{x}{4} - \frac{4}{x}) d x

\frac{( x - 12 ) ( x + 13 )}{x ^{2} - 1}

\frac{( 4 y + x ) ^{3}}{8}

e^{x} (x + i y) (cos (y) + i sin (y))

(1 - y e^{x y}) \cdot (e^{- x y} + x)
