If the integrating factor of the differential equation

\frac{{dy}}{{dx}} + P\left( x \right)y = Q\left( x \right)

x

, then

P\left( x \right)

View answer and explanation

Correct option: C

\frac{1}{x}

Option C (

\frac{1}{x}

) is correct because the integrating factor is given as x, and P(x) can be found by differentiating the logarithm of the integrating factor.
