I've been given
$$4x^3 -2x^2 + x - 3 = 0$$
and I want to convert it into a depressed equation. A depressed equation is an equation that results from reducing the number of roots in a given equation with one unknown by dividing the original equation by the difference of the unknown and a root. However; I know for a fact that you need some sort of divisor in order to do this. The correct answer is:
$$4x^2 + 2x + 3$$
