Lets say you have 5x5. you would just add 5+5+5+5+5. To get a whole number for a fraction you have to do this. lets say you have 8/8 that would be equal to 8 circles and eight of those circles would be shaded in. 8/8 is one whole also 7/1 is a whole. It all depends on the problem you are trying to figure out

If both binomials have the same variables to the same powers, then it is true. In general, multiplying binomials gives four terms, one corresponding to each letter of the FOIL acronym. So, you only get a trinomial when the O and I terms combine.
Factored Form:
f(x) = (x - 2) (x - 8)
Standard Form:
f(x) = x^2 - 10x + 16
