WebNov 10, 2024 · The integrating factor is μ(x) = e ∫ ( 3 / x) dx = e3lnx = x3. 3. Multiplying both sides of the differential equation by μ(x) gives us x3y′ + x3(3 x) = x3(4x − 3) x3y′ + 3x2y = 4x4 − 3x3 d dx(x3y) = 4x4 − 3x3. 4. Integrate both sides of the equation. ∫ d dx(x3y)dx = ∫4x4 − 3x3dx x3y = 4x5 5 − 3x4 4 + C y = 4x2 5 − 3x 4 + Cx − 3. 5. WebSolution for Q5.
