Find the general solution of the following equation. Express the solution explicitly as a function of the independent variable.
Mashcka [7]

Answer:

Therefore the general solution is

2 \sqrt w = 2 ln(x) - 5 \frac1x +c

Step-by-step explanation:

Integration Rule:

  1. \int x^n dx= \frac{x^{n+1}}{n+1}+c
  2. \int \frac1x dx= ln(x) +c

Given differential equation is

x^2 \frac{dw}{dx}= \sqrt{w}(2x+5)

\Rightarrow x^2 dw= \sqrt{w} (2x+5) dx    [ multiplying dx both sides]

\Rightarrow \frac{dw}{\sqrt w}= \frac{(2x+5)}{x^2} dx                [ dividing x^2\sqrt w both sides]

Integrating both sides

\int \frac{dw}{\sqrt w}=\int \frac{(2x+5)}{x^2} dx

\Rightarrow \int w^{-\frac12} dw=\int (\frac{2x}{x^2}+\frac{5}{x^2} )dx

\Rightarrow \int w^{-\frac12} dw=\int \frac{2}{x}dx +\int\frac{5}{x^2} dx

\Rightarrow \frac{w^{-\frac12+1}}{-\frac12+1} =2ln x+5 \frac{x^{-2+1}}{-2+1}+c   [ c is arbitrary constant]

\Rightarrow 2 \sqrt w = 2 ln(x) - 5 \frac1x +c

Therefore the general solution is

2 \sqrt w = 2 ln(x) - 5 \frac1x +c
