expand (-x^2+2x)^2

Solution

expand

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

Solution

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

Solution steps

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

Apply Perfect Square Formula:

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

(- x^{2} + 2 x)^{2} = (- x^{2})^{2} + 2 (- x^{2}) \cdot 2 x + (2 x)^{2}

= (- x^{2})^{2} + 2 (- x^{2}) \cdot 2 x + (2 x)^{2}

Simplify

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

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