Step 1.1

Group the first two terms and the last two terms.

$(x^{3} - 7 x^{2}) - 11 x + 77$

Step 1.2

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

$x^{2} (x - 7) - 11 (x - 7)$

Step 2

Factor the polynomial by factoring out the greatest common factor, $x - 7$ .

$(x - 7) (x^{2} - 11)$
