factor 81-(x+8)^2

Solution

factor

81 - (x + 8)^{2}

Solution

(17 + x) (- x + 1)

Solution steps

81 - (x + 8)^{2}

Factor the number:

81 = 9^{2}

= 9^{2} - (x + 8)^{2}

Apply Difference of Two Squares Formula:

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

9^{2} - (x + 8)^{2} = (9 + (x + 8)) (9 - (x + 8))

= (9 + (x + 8)) (9 - (x + 8))

Simplify

(9 + (x + 8)) (9 - (x + 8)) : (17 + x) (- x + 1)

= (17 + x) (- x + 1)
