Posted by: KAUSTAV D. on 11.09.2020

16pq+2p+15

15pq+15+pq+2p

= 15pq+pq+2p+15

= 16pq+2p+15

=p(16q+2)+15

15pq+15+pq+2p= 16pq+15+2p
15pq+15+pq+2p =16pq+15+2p We can't add further because terms are unlike. Unlike means having different algebraic coefficients

15pq+15+pq+2p

(15pq+pq)+2p+15

(16pq+2p)+15

On taking 2p common

2p(8q+1)+15

15pq+15+pq+2p

(15pq+pq)+2p+15

(16pq+2p)+15

On taking 2p common

2p(8q+1)+15

16pq+2p+15 or 2p(8q+1)+15
15pq+15+pq+2p =16pq+2p+15 This can also be written as 2p(8q+1)+15 Both the answers are correct
16pq+2p+15
16pq+2p+15
15pq+pq+2p+15 16pq+2p+15 like terms are added & it is written in general form
16pq+15+2p

15pq + 15 + pq + 2p

group the like variables = (15pq + pq) + 15 + 2p = 16pq + 15 + 2p = 2p (8q + 1) + 15 (taking 2p common)
