factor (x+2)^2-9

Solution

factor

(x + 2)^{2} - 9

Solution

(x + 5) (x - 1)

Solution steps

(x + 2)^{2} - 9

Factor the number:

9 = 3^{2}

= (x + 2)^{2} - 3^{2}

Apply Difference of Two Squares Formula:

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

(x + 2)^{2} - 3^{2} = ((x + 2) + 3) ((x + 2) - 3)

= ((x + 2) + 3) ((x + 2) - 3)

Simplify

((x + 2) + 3) ((x + 2) - 3) : (x + 5) (x - 1)

= (x + 5) (x - 1)
