Answer 2

Answer:

$15pq - 9p^{2} - 28q^{2}$

Step-by-step explanation:

Subtract 13p² - 4pq +7q²   from 11pq +4p²  -21q²​

 $(11pq +4p^{2} - 21q^{2} ) - (13p^{2} - 4pq + 7q^{2} )$

= $11pq +4p^{2} - 21q^{2} - 13p^{2} + 4pq - 7q^{2}$

= $11pq + 4pq +4p^{2} - 13p^{2} - 21q^{2} - 7q^{2}$

= $15pq - 9p^{2} - 28q^{2}$
