b) 2p² + pq, 7pq - p²​
Please Help me

Answer 1

Answer:

2 + G > 10 (as its resulting a carry 1 on next); Now, possible values of G to get 1 carry at next step is – {G = 8 or 9}.

Answer 2

Question :

Add : 2p² + pq and 7pq - p²

Answer :

$\\ \large \sf \implies p^2 + 8pq$

Solution :

$\large \sf \implies (2p^2 + pq) + ( 7pq - p^2 ) \\ \\\large \sf \implies 2p^2 + pq + 7pq - p^2$

• Combine Like terms :

$\large \sf \implies \color{red}{2p^2} \color{black}+ \color{green}{pq} \color{black}+ \color{green}{7pq} \color{black}- \color{red}{p^2}\\ \\\large \sf \implies \color{red}{(2p^2} \color{black}- \color{red}{p^2} ) \color{black}+ \color{green}{(pq} \color{black}+ \color{green}{7pq}) \\ \\\large \sf \implies \color{red}{p^2} \color{black}+ \color{green}{8pq}$

Hence,

By adding 2p² + pq and 7pq - p²

☞ we got = p² + 8pq.
