Question

4x2-2x / 2x2-1

Answer 1

\[4x^2-2x/2x^2-1\]
is your question

Answer 2

yes so you factor each equation and i dont know hat to do after that

Answer 3

i think multiply 2x^2 from

Answer 4

equation and then take

Answer 5

2x common
did you do these all

Answer 6

No no no and no

Answer 7

Both of you

Answer 8

Parentheses

Answer 9

Oh God @1645323 4x2-2x/2x2-1 is different from (4x2-2x)/(2x2-1)

Answer 10

Final answ 2-[(x-1)/(2x^2-1)

Answer 11

4x2-2x / 2x2-1

You have written: \(4x^{2} - \dfrac{2x}{2x^{2}} - 1\). It appears this is not your intent. Please use parentheses where necessary.

Answer 12

@tkhunny: Is there any thing wrong with the American education system that did not emphasize the importance of parentheses? This is not the first case where I met questions without parentheses like this.

Answer 13

I think it is ONLY a side effect of the student failing to realize that IN-LINE writing is not the same as formatted HAND writing. It's a tricky thing to overcome, as handwriting doesn't FEEL like formatting. In the transition from NATURAL handwriting to in-inline typing, one wants it to be NATURAL. It's not natural to SEE parentheses that were just not necessary when you just wrote the same thing on a piece of paper.

1) Teach Order of Operations (I have U.S. textbooks generations old that give it a go.)

2) Practice in-line typing as a unit that simply was not necessary until the days of mathematics help websites. I have not seen this unit in ANY textbook, ever. Perhaps it is time.
