Factor a+8a^2b-ab

$a + 8 a^{2} b - a b$

Step 1

Factor $a$ out of $a + 8 a^{2} b - a b$ .

Raise $a$ to the power of $1$ .

$a^{1} + 8 a^{2} b - a b$

Factor $a$ out of $a^{1}$ .

$a \cdot 1 + 8 a^{2} b - a b$

Factor $a$ out of $8 a^{2} b$ .

$a \cdot 1 + a (8 a b) - a b$

Factor $a$ out of $- a b$ .

$a \cdot 1 + a (8 a b) + a (- 1 b)$

Factor $a$ out of $a \cdot 1 + a (8 a b)$ .

$a \cdot (1 + 8 a b) + a (- 1 b)$

Factor $a$ out of $a \cdot (1 + 8 a b) + a (- 1 b)$ .

$a (1 + 8 a b - 1 b)$

Step 2

Rewrite $- 1 b$ as $- b$ .

$a (1 + 8 a b - b)$
