The magnetic flux density in a laboratory experiment follows a level curve CCC defined by the equation
3x2y−2y3+5x2=10 3x^2y - 2y^3 + 5x^2 = 10 3x2y−2y3+5x2=10Find an equation of the normal to the curve CCC at the point (2,−1)(2, -1)(2,−1), giving your answer in the form ax+by+c=0ax + by + c = 0ax+by+c=0, where aaa, bbb and ccc are integers.
