expand (-k-1)^2

Solution

expand

(- k - 1)^{2}

Solution

k^{2} + 2 k + 1

Solution steps

(- k - 1)^{2}

Apply Perfect Square Formula:

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

(- k - 1)^{2} = (- k)^{2} - 2 (- k) \cdot 1 + 1^{2}

= (- k)^{2} - 2 (- k) \cdot 1 + 1^{2}

Simplify

(- k)^{2} - 2 (- k) \cdot 1 + 1^{2} : k^{2} + 2 k + 1

= k^{2} + 2 k + 1
