Question

Add: ab – 4a, 4b – ab, 4a – 4b

Answer 1

The addition of ab – 4a, 4b – ab and  4a – 4b = 0

Step-by-step explanation:

We have,

ab – 4a, 4b – ab and  4a – 4b

To add, ab – 4a, 4b – ab and  4a – 4b = ?

∴ ab – 4a, 4b – ab and  4a – 4b

= (ab – 4a) + (4b – ab) +  (4a – 4b)

= ab – 4a + 4b – ab +  4a – 4b

=  (ab - ab) + (– 4a +  4a) + ( 4b – 4b)

= 0 + 0 + 0

= 0

Thus, the addition of ab – 4a, 4b – ab and  4a – 4b = 0

Answer 2

ab- ab-4a+4a+4b-4b
