How do you solve #3x^4=375x#?
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:
The second expression as a trivial solution which is 5, but a third degree polynomial has tree roots (real or not).
so the equation is equivalent to:
The second degree polynom has roots:
