Answer 2

Answer:

$\boxed{ \pink{ \bold{8 {p}^{2} - 5pq + 7 {q}^{2} }}}$

Step-by-step explanation:

$(5p^{2} + 3 {q}^{2} - pq) - (4pq - 4 {q}^{2} - 3 {p}^{2} )$

Whenever there is '-' sign outside the bracket, just remember that, it become + by changing the signs of all terms in bracket.

So,

$5p^{2} + 3 {q}^{2} - pq - 4pq + 4 {q}^{2} + 3 {p}^{2}$

Now, write like terms side-by-side,

$5p^{2} + 3 {p}^{2} - pq - 4pq + 3 {q}^{2} + 4 {q}^{2}$

Now, simply add,

$\bold{8 {p}^{2} - 5pq + 7 {q}^{2} }$
