Program Explanation Given information: The first-order differential equation is x y ′ + 2 y = 6 x 2 y . Explanation: The given differential equation can be rewritten as, d y d x + 2 y x = 6 x 2 y x d y d x + 2 x y = 6 x y Compare the Bernoulli equation with the above equation to obtain the value of P ( x ) and Q ( x ) . P ( x ) = 2 x Q ( x ) = 6 x The value of n is 1 2 and the value of 1 − n is calculated as, 1 − n = 1 − 1 2 = 1 2 Substitute y 1 2 for v and differentiate with respect to x as, v = y 1 2 y = v 2 d y d x = 2 v d v d x The given differential equation can be written as, 2 v d v d x + 2 x v 2 = 6 x v 2 2 v d v d x + 2 x v 2 = 6 x v 2 v ( d v d x + 1 x v ) = 6 x v d v d x + 1</
