Factor 9x^3+18x^2-4x-8

factor

9 x^{3} + 18 x^{2} - 4 x - 8

(x + 2) (3 x + 2) (3 x - 2)

Solution steps

9 x^{3} + 18 x^{2} - 4 x - 8

= (9 x^{3} + 18 x^{2}) + (- 4 x - 8)

Factor out

9 x^{2}

from

9 x^{3} + 18 x^{2} : 9 x^{2} (x + 2)

Factor out

- 4

from

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

= 9 x^{2} (x + 2) - 4 (x + 2)
