# How do you find all the zeros of #F(X)= 3x^2 - 2x^2 + x +4#?

Use Cardano's method to find Real zero:

#x_1 = 1/9(2+root(3)(505+135sqrt(14))+root(3)(505-135sqrt(14)))#

and related Complex zeros...

Assuming that there's a typo in the question...

To make the task of solving the cubic simpler, we make the cubic simpler using a linear substitution known as a Tschirnhaus transformation.

We want to solve:

Then:

Use the quadratic formula to find:

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
