Find the general solution of the given differential equation
Find the general solution of the given differential equation.
Solution
Divide all over by x :
dy/dx + (5/x)y = x^2 - 1
Integrating factor = e^(integral of 5/x)
IF = e^(5ln(x))
IF = e^(ln(x^5))
IF = x^5
Multiply the DE by x^5 all over :
x^5 * [dy/dx + (5/x)y = x^2 - 1]
d/dx ( y * x^5) = x^7 - x^5
Integrating both sides :
y*x^5 = x^8/8 - x^6/6 + C
y = x^3/8 - x/6 + C/x^5 ---> ANSWER
