Thread: simplifing algebraic fractions

can anyone simplify this for me or possibly run me through how to simplify it?

4x + 2 / x² + 4x + 3 * x + 3 / 7x + 5

Thank you

Is this supposed to be

Then the above is equal to:


Notice the common x + 3 in the numerator and denominator. So....

Only if my guess was right. I really wish we could post a sticky about using parenthesis and that it would have even a little effect. But I doubt it would even be read. (sigh)

As with the last example, start by factoring:


As for how to write it, what we were referring to was writing your expressions something like this:
3/(x + 2) times (2x + 4)/x

as opposed to
3/x + 2 times 2x + 4/x
which is confusing.
