Find the solution of differential equation, dy⁄dx = xy + x2, if y = 1 at x = 0.

• A. \(1-\frac{x^2}{2!}+\frac{3x^4}{4!}-\frac{15x^6}{6!}+…\)
• B. \(\frac{x}{1!}+\frac{3x^3}{4!}+\frac{15x^5}{6!}+…\)
• C. \(\frac{x}{1!}-\frac{3x^3}{4!}+\frac{15x^5}{6!}-…\)
• D. \(1+\frac{x^2}{2!}+\frac{3x^4}{4!}+\frac{15x^6}{6!}+..\)
