Finding the maximum bending moment of a beam with M=½ω(lx-x²)

[airmarshal]

hi i want to find out the bending moment of a beam at a distance from one end is given by M=1/2$$\omega$$ (lx-x^2) where $$\omega$$and l are constant. how do we find maximum value and why its maximum value i would realli apreciate it if someone would help me

hi airmarshal! welcome to pf!

(have an omega: ω and try using the X² tag just above the Reply box )

either differentiate wrt x, or complete the square
