- I tried to solve it after first derivative and I get x=0 and a some other equation that when I use the quad formula I get minus in the root so what do I do to solve it

Please walk me step by step on how to do it (we don't have imaginary numbers so don't bring that up)

Also how to put signs on the numbers line when I get minus in the root? (non solveable equation)

Sorry for my English.
