x(25-x)^3

Input

x (25 - x)^3

Roots

x = 0
x = 25

Polynomial discriminant

Δ = 0

Derivative

d/dx(x (25 - x)^3) = (25 - 4 x) (25 - x)^2

Indefinite integral

integral x (25 - x)^3 dx = -x^5/5 + (75 x^4)/4 - 625 x^3 + (15625 x^2)/2 + constant

Global maximum

max{x (25 - x)^3} = 10546875/256 at x = 25/4
