Think about the different things that 5- 2 could mean. using these meanings, what should - 2 -2 mean if u know the answer can u explain how you got it

Is this what you are looking for?
So what I did was that I put the 5 and the two as a whole number, and I just put the minus sign in the middle. Then, I did the "change to the opposite" thing. What u do is u put the five normal then you put a plus sign then a - 2 (negative two), and at the end u just do 5 minus 2.
It's kind of confusing but You'll get it some day :)

Do you need with the x value for the minimum? its always between the two intercepts for a parabola
