Answer:

The solution for partial differential equation \sqrt{p}+\sqrt{q}=2x is z=\frac{(\alpha +2x)^{3}}{3}+y\alpha^{2}+C.

Step-by-step explanation:

Consider the partial differential equation as follows:

\sqrt{p}+\sqrt{q}=2x

\sqrt{p}-2x=-\sqrt{q}

Let \alpha be any arbitrary such that \sqrt{p}-2x=-\sqrt{q}=\alpha.

This is of the form F_{1}(x,p)=F_{2}(x,q)=\alpha.

\sqrt{p}-2x=\alpha

\sqrt{p}=\alpha+2x

p=(\alpha +2x)^{2} (Squaring both side) ...... (1)

-\sqrt{q}=\alpha

q=a^{2} (Squaring both side) ...... (2)

Since dz=pdx+qdy

dz=(\alpha +2x)^{2}dx+{\alpha}^{2}dy (From (1) and (2))

Integrate both the sides.

z=\frac{(\alpha +2x)^{3}}{3}+y\alpha^{2}+C, where C is the integration constant.
