dx/dt = -4x-2x^2
find the find the maximum rate of change of x (t)
i know its could be very easy but i just have no ideas at all
---------------------------------------
give the values of n and C for which y=Cx^n is a solution of the equation x^3 dy/dx -10 x^2 y =0
the answer is, C=0 and n could be any no. , but why?
thx
