Answer:
b (a + 2) (a - 1)
Step-by-step explanation:
1. First you need to factor out b from the equation because it is the one factor that they all have in common.
2ab + a²b - 2b - ab
b (2a + a² - 2 - a)
2. Then you just factor 2a + a² - 2 - a and remember the b
b (2a + a² - 2 - a)
b (a + 2) (a - 1)
check your answer:
b (a + 2) (a - 1)
b (a²- a + 2a - 2)
a²b - ab + 2ab - 2b
2ab + a²b -2b - ab
hope this helps!!
