Question

Some help with simplifying.

(5/a^2) - (4/(a*b)) + (7/b^2)

Answer 1

\[\left( \frac{ 5 }{ a^2 } - \frac{ 4 }{ ab } + \frac{ 7 }{ b^2 } \right)\]

Answer 2

I just need help starting it. I don't want you to give me the answer just like that

Answer 3

I dont' see much factoring there btw

Answer 4

5 and 7 are primes
4 has two factors, neither one is either 5 or 7

and the denominators can only be paired with another, but not all three

Answer 5

Hmm well it appears the question was simplifying, any idea how I can simplify it?

Answer 6

You have an expression with three terms. To simplify it you want to make into an expression with one term.

Answer 7

Hint: common denominator
