(a + 5) (a - 5) = a2 - 25
7(a + 3) = 7*a + 7*3 = 7a + 21

(a + 5) (a - 5) = a2 - 25
7(a + 3) = 7*a + 7*3 = 7a + 21
(6 + 1) + 8 = 6 + (1 + 8) is the associative property of addition
This is the associative law for addition: If a, b, c are any numbers then: a + (b + c) = (a + b) + c
The way you have written this makes it impossible to evaluate. what math operation is involved after cosx plus 1? is that added, subtracted, multiplied or divided by 2 cos2x-3cos2 etc.
