Answer 1

$\huge{\red{A}\pink{n}\blue{s}\purple{w}\green{e}\pink{r}}</p><p>$

4p²-7pq + 4q²-3+p² - 8pq + 5+ 6q²+6- 2pq – 5q² + 2p²

=4p²−7pq+4q²+−3+p²+−8pq+5+6q²+6+−2pq+−5q²+2p²

=(4p²+p²+2p²)+(−7pq+−8pq+−2pq)+(4q²+6q²+−5q²)+(−3+5+6)

=7p²+−17pq+5q²+8

$\bf{\red{❥Hope \: }\pink{it \: }\blue{helps \: }\purple{you \: }\green{.....}}$

Answer 2

=4p²−7pq+4q²+−3+p²+−8pq+5+6q²+6+−2pq+−5q²+2p²

=(4p²+p²+2p²)+(−7pq+−8pq+−2pq)+(4q²+6q²+−5q²)+(−3+5+6)

=7p²+−17pq+5q²+8
