Question 3(iii)
Add the following:
(iii) $2 p^{2} q^{2} - 3 p q + 4, 5 + 7 p q - 3 p^{2} q^{2}$

Open in App

Solution

(iii) $2 p^{2} q^{2} - 3 p q + 4, 5 + 7 p q - 3 p^{2} q^{2}$
$S u m = 2 p^{2} q^{2} - 3 p q + 4 - 3 p^{2} q^{2} + 7 p q + 5 (a d d i n g l i k e t e r m s)$

Hence, the sum is $- p^{2} q^{2} + 4 p q + 9.$
