Basic Math Examples

$b^{3} + 5 b^{2} - 20 b$

Step 1

Factor $b$ out of $b^{3}$ .

$b \cdot b^{2} + 5 b^{2} - 20 b$

Step 2

Factor $b$ out of $5 b^{2}$ .

$b \cdot b^{2} + b (5 b) - 20 b$

Step 3

Factor $b$ out of $- 20 b$ .

$b \cdot b^{2} + b (5 b) + b \cdot - 20$

Step 4

Factor $b$ out of $b \cdot b^{2} + b (5 b)$ .

$b (b^{2} + 5 b) + b \cdot - 20$

Step 5

Factor $b$ out of $b (b^{2} + 5 b) + b \cdot - 20$ .

$b (b^{2} + 5 b - 20)$
