factor x^3-4x^2-2x+8

Solution

factor

x^{3} - 4 x^{2} - 2 x + 8

Solution

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

Solution steps

x^{3} - 4 x^{2} - 2 x + 8

= (x^{3} - 4 x^{2}) + (- 2 x + 8)

Factor out

x^{2}

from

x^{3} - 4 x^{2} : x^{2} (x - 4)

Factor out

- 2

from

- 2 x + 8 : - 2 (x - 4)

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