Correct Answer: $1$

Solution : Given: $x^{2}+y^{2}+6x+5=4(x-y)$
⇒ $x^{2}+y^{2}+6x+5-4x+4y=0$
⇒ $x^{2}+y^{2}+2x+5+4y=0$
⇒ $x^{2}+2x+1+y^{2}+4y+4=0$
⇒ $x^{2}+2×x×1+1+y^{2}+2×y×2+4=0$
⇒ $(x+1)^{2}+(y+2)^{2}=0$
⇒ $x$ = – 1 and $y$ = – 2 [If the sum of two square terms is zero, then each term will also be zero]
So, $(x-y) = (–1–( –2))=1$
Hence, the

Solution : Given, $2\text{p} + \text{q} = 19$ and $\text{8p}^3 + \text{q}^3 = 361$
We have to find the value of pq
Consider $2\text{p} + \text{q} = 19$
Cubing both sides,
⇒ $\text{(2p+q)}^3 = \text{19}^3$
⇒ $(\text{2p})^3 + \text{q}^3 + \text{3(2p)(q)(2p+q)} = 6859$
⇒ $\text{8p}^3 + \text{q}^3
