Sheer and bending moment diagrams

ok so for concentrated loads the sheer diagram is constant meaning are straight horizontal lines and the bending moment diagram is linear. when there are evenly distributed loads sheer diagram is linear and bending moment diagram is quadratic. I am thinking that when there is a load distributed linearly like in the picture below the sheer diagram would be quadratic and the bending moment diagram cubic. I am kind of stuck on this problem all the variables make it harder to visualize what is happening I have done this so far but i got stuck when trying to find the bending moment.

I cannot make sense of that.

Seems reasonable. Can you write the equations?
