Are you just trying to simplify these? If so:
1. multiply the tops together and multiply the bottoms together:
(2a * 7a²)/(3 * 5) = 2a³/15
2. Pull 3a out of both terms on top, then it'll cancel with the bottom:
3a(6a² +a)/3a = 6a² + a
3. In this one, you can only simplify the second part:
6a² + 3a(a)/3a = 6a² + 3a
4. same method as 3
5. This is like the quadratic formula:
(3a - 2b)*(3a - 2b) = 9a² - 12ab + 4b²
6. are you missing some parentheses in this one?
7. cancel out one "a" from the top and bottom:
3a/2
8. Square the top and the bottom:
25/y²
