(- x - 2)^{2}

Solution

x^{2} + 4 x + 4

Solution steps

(- x - 2)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

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

= x^{2} + 4 x + 4
