Question

I is tough problem.............​

Answer 1

Answer:

$\: \: \: \: \: p + q \\ = 2 {x}^{2} + 3xy + 5 {y}^{2} + 14 {x}^{2} + 37xy + 20 {y}^{2} \\ = 16 {x}^{2} + 40x + 25 {y}^{2} \\ = (4x) {}^{2} + 2(4x)(5y) + (5y) {}^{2} \: \: \\ = (4x + 5y) {}^{2}$

Answer 2

Answer:

(4x+5y)²

Step-by-step explanation:

P+Q=2x²+3xy+5y²+14x²+37xy+20y²

=16x²+40xy+25y²

=(4)²+2(4x)(5y)+(5)²

=(4x+5y)²=ANS
