expand (-2x-2)^2

Solution

expand

(- 2 x - 2)^{2}

Solution

4 x^{2} + 8 x + 4

Solution steps

(- 2 x - 2)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

(- 2 x)^{2} - 2 (- 2 x) \cdot 2 + 2^{2} : 4 x^{2} + 8 x + 4

= 4 x^{2} + 8 x + 4
