##### 2 Answers

#### Explanation:

This is an equation with a single variable, therefore we can reach its sollution through algebric operations. First, we must apply the same operation to both sides of the equation. Let's divide each by

On the left side, we will have

Finish by taking the cubic root of both sides of the equation:

#### Explanation:

The second expression as a trivial solution which is 5, but a third degree polynomial has tree roots (real or not).

Let's divide

so the equation is equivalent to:

The second degree polynom has roots:
