factor (x+1)^2-81

Solution

factor

(x + 1)^{2} - 81

Solution

(x + 10) (x - 8)

Solution steps

(x + 1)^{2} - 81

Factor the number:

81 = 9^{2}

= (x + 1)^{2} - 9^{2}

Apply Difference of Two Squares Formula:

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

(x + 1)^{2} - 9^{2} = ((x + 1) + 9) ((x + 1) - 9)

= ((x + 1) + 9) ((x + 1) - 9)

Simplify

((x + 1) + 9) ((x + 1) - 9) : (x + 10) (x - 8)

= (x + 10) (x - 8)
