If you got an answer, but can't explain it, did you
(a) just guess?
(b) cheat?
and, did you ever hear of parentheses?
My best guess is
[(3x-7)/x^2] / (x^2/(2+2/x))
= (3x-7)/x^2 * (2+2/x)/(x^2)
= (3x-7)(2+2/x)
= (3x-7) * (2x+2)/x
= (6x^2-8x-14)/x
= 6x - 8 - 14/x
If that is not what you had in mind, then
(a) mosey on over to wolframalpha.com and type in your expression. Use enough parentheses until it interprets your input correctly.
(b) use parens in the future when typing complicated stuff online
Simplify the complex fraction and show all the steps that you used to solve this problem:
3x-7/x^2/ x^2/2+2/x
So it's kinda confusing but the x^2/2+2/x go under the first x^2
The answer I got was
2(3x-7) / x(x^3+4) I just don't know how to explain it

Ok firstly, I'm not very good at utilizing parentheses but I understand how that could've been more helpful. Secondly, I used mathway to type in the equation to get my answer it just wouldn't show me the steps into getting that answer, so I couldn't understand it. That's why I needed some help. Thirdly, thank you for ur help oobleck even though u were a bit rude.
