Please solved accurate please neat and clear so i can understand. Thanks

Extracted text: A structural component as part of a lifting device is 2 metres long and is subjected to downward forces resulting in a bending moment equation given by: M = -35x? + 20x +20x -1 M = value of the bending moment x = distance from L.H.S. of beam Determine a first order differential equation and use it to find the value of x for which the bending moment is a minimum. Prove this to be the minimum value using higher order derivatives. State any boundary conditions
