Add : ab-4a,4b-ab,4a-4b
To add : ab-4a,4b-ab,4a-4b
Simplify given expression
On combining the like terms and adding them we get
=ab–4a+(4b–ab)+(4a–4b)=ab–4a+4b–ab+4a–4b=ab–ab–4a+4a+4b–4b=ab(1-1)+a(4–4)+b(4–4)=ab(0)+a(0)+b(0)=0
Hence, required answer is 0.
Question 2 (ix)
Add:
ab - 4a, 4b - ab, 4a - 4b
