Hi, there-- THE PROBLEM: Evaluate a^2-b divided by 3 for a=-9 and b=-6 A SOLUTION: I made the assumption that you expression looks like this:You would type this as (a^2-b)/3 to show that everything is divided by 3. The way you typed it, only b is divided by 3. If you have a different expression, let me know and I'll help you sort it out. To evaluate , substitute -9 for a and -6 for b. Hope this helps!
