Question

sum of a-b+ab,b+c-bc,c-a-ac​

Answer 1

Step-by-step explanation:

a-b+ab+b+c+bc+c-a-ac

2c+ab-bc-ac

Answer 2

Sum of a−b+ab ,  b+c−bc and c−a−ac is 2c+ab−ac−bc.

Sum of a−b+ab ,  b+c−bc and c−a−ac

=(a−b+ab)+(b−c−bc)+(c−a−ac)

=a−b+ab+b+c−bc+c−a−ac

Rearranging and collecting like terms, we get:

=a−a−b+b+c+c+ab−bc−ac

=2c+ab−ac−bc
