If x ~d y ~d x -y x=6 x, 0 x 2 , then general solution of the differential equation is
Options
- Ay= x+3 x^2+ c , where c is a constant of integration.
- By+ x=3 x^2+ c , where c is a constant of integration.
- Cy=3 x^2 x+ x , where c is a constant of integration.
- Dy x=3 x^2+ c , where c is a constant of integration.
Correct answer
D. y x=3 x^2+ c , where c is a constant of integration.
Step-by-step solution
aligned & x ~d y ~d x -y x=6 x & ~d y ~d x -( x) y=6 x x aligned This equation is of the form d y ~d x + p y= Q If = e ^ pdx = e ^ - x d x = e ^ x x = x Solution of given equation is aligned & y x= 6 x x x ~d x+ c & y x= 6 x ~d x+ c & y x=3 x^2+ c aligned
