I am finding the coordinates of stationary point of the equation y = x^4 - 2x^3 - 5x^2 + 6.
First, I found y´ = 4x^3 - 6x^2 - 10x
Then I was going to find all the x coordinates but now I am stumped.
So I´ve got, 4x^3 - 6x^2 - 10x = 0
Then, 2x(2x^2 - 3x - 10) = 0
Now I am trying trial and error but I can´t get the damn thing right and this will undoubtedly take me til doomsday unless somebody helps me figure this out.
