Q. Observe the following statements A:Interating factor of $\frac{dy}{dx} + y = x^{2}$ is $e^{x}$ R: Integrating factor of $\frac{dy}{dx} + P(x)y = Q(x)$ is $e^{\int_{}^{}{P(x)dx}}$ Then, the true statement among the following is

A) A is true, R is false
B) A is false, R is true
C) A is true, R is true, $R \Rightarrow A$
D) A is false, R is false
Explanation

(c)
Given, $\frac{dy}{dx} + y = x^{2}$
$\therefore$ $IF = e^{\int_{}^{}{1\ \ dx}} = e^{x}$
$\frac{dy}{dx} + P(x)y = Q(x)$
$\therefore$ $IF = e^{\int_{}^{}{P(x)dx}}$
$\therefore$ Both statements A and B are true and $R \Rightarrow A$
