expand (x-x^3)^2

Solution

expand

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

Solution

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

Solution steps

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

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

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

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

Simplify

x^{2} - 2 x x^{3} + (x^{3})^{2} : x^{2} - 2 x^{4} + x^{6}

= x^{2} - 2 x^{4} + x^{6}
