Let the differential 2-form Ω = (3x² + 2xy + 6y²)dx∧dy be defined in a star-like domain

.
(a) Is Ω closed?
(b) Is Ω exact on D? If so, find a differential 1-form Φ such that Ω = dΦ.
◦ Ω is both closed and exact, Φ = (xy² + 2y³)dx + x³dy
◦ Ω is neither closed nor exact
◦ Ω is both closed and exact, Φ = - (xy² + 2y³)dx + x³dy
◦ Ω is both closed and exact, Φ = x³dx - (xy² + 2y³)dy
◦ Ω is closed but not exact
