expand 2pix(x-x^{17})

expand

2 π x (x - x^{17})

- 2 π x^{18} + 2 π x^{2}

Solution steps

2 π x (x - x^{17})

Apply the distributive law:

a (b - c) = ab - a c

a = 2 π x, b = x, c = x^{17}

= 2 π xx - 2 π x x^{17}

= 2 π xx - 2 π x^{17} x

Simplify

2 π xx - 2 π x^{17} x : - 2 π x^{18} + 2 π x^{2}

= - 2 π x^{18} + 2 π x^{2}

\frac{x - 6}{( x - 1 ) ( x + 4 )}

sin (2) (x + \frac{π}{3})

\frac{4 x - x ^{2}}{( x + 2 ) ^{2}}

e^{- x^{2} - y^{2}} y (1 - 2 x^{2})

(5 x^{2} + 2 y) d x
