expand (y+ey+e^2y)^3

expand

(y + ey + e^{2} y)^{3}

e^{6} y^{3} + 3 e^{5} y^{3} + 6 e^{4} y^{3} + 7 e^{3} y^{3} + 6 e^{2} y^{3} + 3 e y^{3} + y^{3}

Solution steps

(y + ey + e^{2} y)^{3}

(y + ey + e^{2} y)^{3} = (y + ey + e^{2} y) (y + ey + e^{2} y) (y + ey + e^{2} y)

= (y + ey + e^{2} y) (y + ey + e^{2} y) (y + ey + e^{2} y)

Expand

(y + ey + e^{2} y) (y + ey + e^{2} y) (y + ey + e^{2} y) : e^{6} y^{3} + 3 e^{5} y^{3} + 6 e^{4} y^{3} + 7 e^{3} y^{3} + 6 e^{2} y^{3} + 3 e y^{3} + y^{3}

= e^{6} y^{3} + 3 e^{5} y^{3} + 6 e^{4} y^{3} + 7 e^{3} y^{3} + 6 e^{2} y^{3} + 3 e y^{3} + y^{3}

(1 - 2 x) \cdot e^{x}

(10, 8, - 7) (x, 0, z)

\frac{P ( x )}{( x + 1 ) ^{3} ( 2 x + 5 )}

- 6 \cdot (5 e^{- 2 x} + 7 e^{3 x})
