factor-x^2-4x-4

Solution

factor

- x^{2} - 4 x - 4

Solution

- (x + 2)^{2}

Solution steps

- x^{2} - 4 x - 4

Break the expression into groups

= (- x^{2} - 2 x) + (- 2 x - 4)

Factor out

- x

from

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

Factor out

- 2

from

- 2 x - 4 : - 2 (x + 2)

= - x (x + 2) - 2 (x + 2)

- x - 2 : - (x + 2)

= (x + 2) (- (x + 2))

Simplify

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

= - (x + 2)^{2}
