(x + 7)(x - 4) = x^2 - 4x + 7x - 28 = x^2 + 3x - 28
(5-4)-3 = -2. If we move the parenthesis, as is defined by what the associative property is, 5-(4-3) = 4. No matter what, you always approach mathematical equations or expressions using PEMDA. We have to do what's inside the parenthesis first, which is why we end up with 2 different solutions using subtraction.
