factor x^3+8x^2-x-8

Solution

factor

x^{3} + 8 x^{2} - x - 8

Solution

(x + 8) (x + 1) (x - 1)

Solution steps

x^{3} + 8 x^{2} - x - 8

= (x^{3} + 8 x^{2}) + (- x - 8)

Factor out

x^{2}

from

x^{3} + 8 x^{2} : x^{2} (x + 8)

Factor out

- 1

from

- x - 8 : - (x + 8)

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