expandard
form.​

Answer 1

Step-by-step explanation:

=(p+2q+2)^2

( it is in the form of (a+b+c)^2

we know that

=(a+b+c)^2=a^2+b^2+c^2+2ab+2bc+2ca (p+2q+2)^2=p^2+(2q)^2+2^2+2(p.2q)+2(2q.2)+2.2p

= p^2+4q^2+4+4pq+8q+4p

=(p+2q+2)^2=p^2+4q^2+4+4pq+8q+4p

hope this helps you mark me as brainliest.

Answer 2

Step-by-step explanation:

=a²+b²+c²+2ab+2bc+2ac

=p²+2q²+2²+2×p×2q+2×2q×2+2×p×2

=p²+4q²+4+4pq+8q+4p
