Verify that the given differential equation is not exact. ( x2 + 2xy - y2) dx + (12 + 2xy - x2) dy = 0 If the given DE is written in the form M(x, y) dx + N(x, y) dy = 0, one has My Ny = -Select--- Since My and N v are Ifequal, the equation is not exact. are not Multiply the given differentur cyuuuon by the integrating factor M(x, y) = (x + y)and verify that the new equation is exact. If the new DE is written in the form M(x, y) dx + N(x, y) dy = 0, one has My = Ny = Since My and N are not equal, the equation is exact. Solve
