Answer 2

Answer:

The factors of a²-b+ab-a are (a-1) and (a+b).

Step-by-step explanation:

Factorize:

Factorize means finding the highest common factor of each of the terms in the expression.

Types of Factorization:

There are 4 types of factorization

• Greatest common factor
• Grouping method.
• The difference in two squares.
• The sum or difference in cubes.

• Given expression

           a²-b+ab-a

           a²-a-b+ab

   Take out common a from first two values and take out common b from    last two values

          a(a-1)+b(-1+a)

           a(a-1)+b(a-1)

              (a-1)(a+b)

   Hence, a²-b+ab-a = (a-1)(a+b)
