expand-x(x-3x^3+xy-y^2)

expand

- x (x - 3 x^{3} + x y - y^{2})

- x^{2} + 3 x^{4} - x^{2} y + x y^{2}

Solution steps

- x (x - 3 x^{3} + x y - y^{2})

Distribute parentheses

= - xx - x (- 3 x^{3}) - xx y - x (- y^{2})

Simplify

- xx - x (- 3 x^{3}) - xx y - x (- y^{2}) : - x^{2} + 3 x^{4} - x^{2} y + x y^{2}

= - x^{2} + 3 x^{4} - x^{2} y + x y^{2}

- 2 1^{2}

(- 17 x^{2} + 2 x - 3) + (2 x^{2} - 31 x - 9)

78 \cdot 26

4 x^{2} + 6 x - 10 x^{3}

e^{2 + 3 l n (2)}
