expand (-2-a)^2

Solution

expand

(- 2 - a)^{2}

Solution

4 + 4 a + a^{2}

Solution steps

(- 2 - a)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

(- 2)^{2} - 2 (- 2) a + a^{2} : 4 + 4 a + a^{2}

= 4 + 4 a + a^{2}
