Solution
The correct option is B 5a+b
We have to find sum of (4a+5b),(−6a+2b),(7a−6b)∴ required sum =(4a+5b)+(−6a+2b)+(7a−6b)
=(4a−6a+7a)+(5b+2b−6b)
=5a+b
We have to find sum of (4a+5b),(−6a+2b),(7a−6b)
∴ required sum =(4a+5b)+(−6a+2b)+(7a−6b)
=(4a−6a+7a)+(5b+2b−6b)
=5a+b
=(4a−6a+7a)+(5b+2b−6b)
=5a+b
