Factor x^3-9x^2+4x-36

$x^{3} - 9 x^{2} + 4 x - 36$

Step 1

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(x^{3} - 9 x^{2}) + 4 x - 36$

Factor out the greatest common factor (GCF) from each group.

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

Step 2

Factor the polynomial by factoring out the greatest common factor, $x - 9$ .

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