Answer 1

$\huge \sf \pink{ \underline{ \underline{Answer}}}$

We will Subtract 9p² from 4pq-6p²-2p²

$\sf9 {p}^{2} - 4pq - 6 {p}^{2} - 2 {q}^{2}$

$\sf = 9 {p}^{2} - (4pq - 6 {p}^{2} - 2 {q}^{2} )$

$\sf = 9 {p}^{2} - 4pq + 6 {p}^{2} + 2 {q}^{2}$

We will add 9p² and 6p²

$\sf = 15 {p}^{2} - 4pq + 2 {q}^{2}$

Answer 2

Answer:

Step-by-step explanation:

4pq - 6p² - 2p² ,9p².

9p²  =   -( 4pq - 6q² - 2p²)

9p²  =    4pq+ 6p² + 2p².

  =    11p² - 4pq+ 6q²

  =    11p² + 6q² - 4pq.
