Explanation Given Information: The differential equation is; y ′ − 2 x y = x The match provided is; ( a ) y = C e x 2 ( b ) y = − 1 2 + C e x 2 ( c ) y = x 2 + C ( d ) y = C e 2 x If y = f ( x ) is the solution of the given differential equation, then it should satisfy the differential equation. Let h ( x ) = x n , According to polynomial rule of differentiation , h ′ ( x ) = n x n − 1 . Consider the given differential equation: y ′ − 2 x y = x Now consider the solution is y = C e x 2 then according to primary conditions this y = C e x 2 should satisfy y ′ − 2 x y = x as; ( C e x 2 ) ′ − 2 x ( C e x 2 ) = x d ( C e x 2 ) d x − 2 x ( C e x 2 ) = x C 2 x e x 2 − 2 x ( C e x 2 ) = x 0 ≠ x Therefore, the given equation does not satisfy the given differential equation. Hence, match (a) is incorrect. Consider the solution is y = x 2 + C then according to primary conditions this y = x 2 + C should satisfy y ′ − 2 x y = x as; ( x 2 + C ) ′ − 2 x ( x 2 + C ) = x d ( x 2 + C ) d x − 2 x ( x 2 + C ) = x 2 x − 2 x ( x 2 + C ) ≠ x So, y = x 2 + C is not a solution of equation y ′ − 2 x y = x
