Given the following question:


(5-3x)^2

Find the derivative:


\begin{gathered} (5-3x)^2 \\ (d)/(dx)\mleft(\mleft(5-3x\mright)^2\mright) \\ (5-3x)^2=2\mleft(5-3x\mright)(d)/(dx)\mleft(5-3x\mright) \\ 2\mleft(5-3x\mright)(d)/(dx)\mleft(5-3x\mright) \\ (5-3x)=-3 \\ 2\mleft(5-3x\mright)\mleft(-3\mright) \\ 2*-3=-6 \\ -6\mleft(5-3x\mright) \\ =-6\mleft(5-3x\mright) \end{gathered}

The derivative is -6(5-3x) (I'm only able to answer one question per session)
