Question 39

The magnetic flux density in a laboratory experiment follows a level curve $C$ defined by the equation

3x^2y - 2y^3 + 5x^2 = 10

Find an equation of the normal to the curve $C$ at the point $(2, - 1)$ , giving your answer in the form $a x + b y + c = 0$ , where $a$ , $b$ and $c$ are integers.
