Answer 1

Answer:

hope it will help you

Step-by-step explanation:

$we \: have \: to \: simplify \: \\ 9 {p}^{2} - 6p + 6 - 7 {p }^{2} - 3p - 11 \\ + 5p - 12p + 2 - 15p + 22 + 4 {p}^{2} - 11 \\ collecting \: the \: like \: term \\ (9 {p}^{2} - 7 {p}^{2} + 4 {p}^{2}) + (5p - 6p - 3p - 15p) \\ (6 - 11 + 2 + 22 - 11) \\ (13 {p}^{2} - 7 {p}^{2}) + (5p - 24p) + (30 - 22) \\ 6 {p}^{2} + ( - 19p) + 8 \\ 6 {p}^{2} - 19p + 8$
