Graphing Inquiry - Scaling function, then graphing it (and conserving units)

I want to scale M(x) equation by a scalar (0.805). Is there a way to do this without making my expressions unitless? After searching online for info about the error statement, I could not find a workaround.

 

Note: whenever 0.805 is not applied to M(x) the equation graphs properly. M(x) is defined in kip-ft.

Need to specify units in the output of M(x):

 

 

PS  Are you sure both P2tr and P3tr should both be 32?

    I see... Will have to make a note to myself about this one. Thank you very much. Yes, operating under the assumption P2tr and P3tr are fixed at 32 kip to simulate a fatigue truck loading by AASHTO LRFD standard.
