#-17/2+8/(xv^2)=8x^-1v^-2-17/2#

#(17x^2v^3-16xv) -: (-2x^2v^3)=(17x^2v^3-16xv)/(-2x^2v^3)#

We can undo the fraction into two separate fractions:

#(17x^2v^3)/(-2x^2v^3)-(16xv)/(-2x^2v^3)#

And now we can cancel terms:

#(17cancelx^2cancelv^3)/(-2cancelx^2cancelv^3)-(16cancelxcancelv)/(-2x^cancel2v^cancel3)=-17/2+8/(xv^2)#

We can write this a bit neater this way:

#-17/2+8/(xv^2)=8x^-1v^-2-17/2#
