Answer 1

Answer:

Use grouping to factorise the numerator and take out the common factor ax in the denominator

(ax−ab)+(x−b)

ax2−abx

=

a(x−b)+(x−b)

ax(x−b)

Take out common factor (x−b) in the numerator

=

(x−b)(a+1)

ax(x−b)

Cancel the common factor in the numerator and the denominator to give the final answer

=

a+1

ax
