I would turn the big fraction bar between the top fraction and the bottom fraction into a divide symbol and set them up horizontally.
then you flip the 2nd equation. and im lost from there
Then you'll want to flip the second fraction and multiply, because we don't traditionally divide fractions.
OK - at that point, you'll want to factor every thing that can be factored.
the 5 cancels out and the 15 turns into a 3
That's right - what else cancels?
the 3 turns into a1 and the 6 turns into a 2
No, we can't do that. Remember, things only factors (things being multiplied) can cancel. Sums (things being added) and differences (things being subtracted) can't cancel.
**No, we can't do that. Remember, only factors (things being multiplied) can cancel. Sums (things being added) and differences (things being subtracted) can't cancel. sorry for the typo
That's why we have to factor first - to turn things into factors so that they can cancel.
the (x-3) cancels?
That's right! :)
At this point, we've got this, but there are a few more things that can cancel |dw:1332643898303:dw|
and I'm looking specifically at the x and y on the bottom of the first fraction with the x and y on the top of the second fraction.
you cancel out the exponent ?
You can, but which ones?
y^2 and the x^2
Yes! :) |dw:1332644149276:dw|
And you would probably want to leave it in factored form to let whoever is checking your answer know that it can't be simplified any further.
Does what we did make sense?
