factor x^9-x^8-4x+4

factor

x^{9} - x^{8} - 4 x + 4

(x - 1) (x^{4} + 2) (x^{4} - 2)

Solution steps

x^{9} - x^{8} - 4 x + 4

= (x^{9} - x^{8}) + (- 4 x + 4)

Factor out

x^{8}

from

x^{9} - x^{8} : x^{8} (x - 1)

Factor out

- 4

from

- 4 x + 4 : - 4 (x - 1)

= x^{8} (x - 1) - 4 (x - 1)

Factor out common term

x - 1

= (x - 1) (x^{8} - 4)

Factor

x^{8} - 4 : (x^{4} + 2) (x^{4} - 2)

= (x - 1) (x^{4} + 2) (x^{4} - 2)

e (3 sin (x))
