Question

4p square q - 3pq+ 5pq square - 8p+7q -10 from 18-3p -11q +5pq -2pq square +5p square q

Answer 1

/* It may be like this */

$Let \: A = 4p^{2}q - 3pq+5pq^{2} - 8p + 7q - 10$

$and \: B = 18-3p-11q+5pq-2pq^{2} + 5p^{2}q$

/* According to the problem given */

$B - A \\= 18-3p-11q+5pq-2pq^{2} + 5p^{2}q - (4p^{2}q - 3pq+5pq^{2} - 8p + 7q - 10 )$

$= 18-3p-11q+5pq-2pq^{2} + 5p^{2}q - 4p^{2}q + 3pq-5pq^{2} + 8p - 7q + 10$

$=18+10+(-3+8)p+(-11-7)q+(5+3)pq+(-2-5)pq^{2}+(5-4)p^{2}q\\= 28+5p-18q+8pq-7pq^{2}+p^{2}q$

Therefore.,

$\red{ Required \: expression }\\ \green { </p><p>28+5p-18q+8pq-7pq^{2}+p^{2}q }$
