$4 x^{3} (16 x^{5}) + 4 x^{3} (40 x^{4}) + 4 x^{3} (44 x^{3}) + 4 x^{3} (26 x^{2}) + 4 x^{3} (8 x) + 4 x^{3}$

Step 20.6

Factor $4 x^{3}$ out of $4 x^{3}$ .

$4 x^{3} (16 x^{5}) + 4 x^{3} (40 x^{4}) + 4 x^{3} (44 x^{3}) + 4 x^{3} (26 x^{2}) + 4 x^{3} (8 x) + 4 x^{3} (1)$

Step 20.7

Factor $4 x^{3}$ out of $4 x^{3} (16 x^{5}) + 4 x^{3} (40 x^{4})$ .

$4 x^{3} (16 x^{5} + 40 x^{4}) + 4 x^{3} (44 x^{3}) + 4 x^{3} (26 x^{2}) + 4 x^{3} (8 x) + 4 x^{3} (1)$

Step 20.8

Factor $4 x^{3}$ out of $4 x^{3} (16 x^{5} + 40 x^{4}) + 4 x^{3} (44 x^{3})$ .

$4 x^{3} (16 x^{5} + 40 x^{4} + 44 x^{3}) + 4 x^{3} (26 x^{2}) + 4 x^{3} (8 x) + 4 x^{3} (1)$

Step 20.9

Factor $4 x^{3}$ out of $4 x^{3} (16 x^{5} + 40 x^{4} + 44 x^{3}) + 4 x^{3} (26 x^{2})$ .

$4 x^{3} (16 x^{5} + 40 x^{4} + 44 x^{3} + 26 x^{2}) + 4 x^{3} (8 x) + 4 x^{3} (1)$

Step 20.10

Factor $4 x^{3}$ out of $4 x^{3} (16 x^{5} + 40 x^{4} + 44 x^{3} + 26 x^{2}) + 4 x^{3} (8 x)$ .

$4 x^{3} (16 x^{5} + 40 x^{4} + 44 x^{3} + 26 x^{2} + 8 x) + 4 x^{3} (1)$

Step 20.11

Factor $4 x^{3}$ out of $4 x^{3} (16 x^{5} + 40 x^{4} + 44 x^{3} + 26 x^{2} + 8 x) + 4 x^{3} (1)$ .

$4 x^{3} (16 x^{5} + 40 x^{4} + 44 x^{3} + 26 x^{2} + 8 x + 1)$
