i need to work out this fraction:
3/2x-1 - 4/3x-1
i can do the first part and worked it out and you get a quadratic equation as shown in my picture:
when i type in to my calculator 36-4x6x6 it =-108?
-108 doesn't work!!! why is it coming up with this? have i started my quadratic equation wrong?
help would be much appreciated!!!!
