I have the following equation:
And I need to find the real solution(s) to said equation, but I don't know how. It's for homework and I don't know how to find a solution to the equation, and Newton-Raphson seems like an unlikely solution if I'm going to solve this equation in a mid-term.
I think there's a way to know if an equation has more than one real root, but I don't remember how to, if anyone wants to explain to me if this is true I will be grateful.
I want to learn an "easy" way of solving these kind of equations without the use of computational aids. I don't want the solution but a way to get to the solution and with a simple calculator punch the numbers at the end and find the answer. Any ideas?
