do u remember how to add and subtract fractions with different denominators

>> No.10195262

No I don't. How do you do that again? Something about a "well chosen one"?

>OP cannot subtract fractions when the denominators are different

[math] \frac{2}{s + 4} - \frac{1}{s + 1} = \frac{2(s + 1) - (s + 4)}{(s + 1)(s + 4)} = \frac{s - 2}{s^2 + 5s + 4} [/math]

You can also do this in reverse. It's called partial fraction decomposition.
