Hi;

There are probably a couple of ways to get there:

1) Multiply top and bottom by a.

1) Multiply top and bottom by a2.

bronxsystem · 2014-01-21 04:30:04

from the last one? 1+a/a * a2/1-a2

multiply both by a?

Hi;

No, I was starting from the beginning.

Now you multiply top and bottom of that by a2.

Bob · 2014-01-21 04:52:58

Is that a2 really

?

Hi Bob;

Hmmm, that is probably true.

Latexify, latexify, latexify. Our lives are frittered away by ascii, latexify!

Years of teaching pupils with squiggly writing. I'm used to powers appearing in random places.

By the way. Who were you quoting with that latexify quote?

I was trying to quote Henry David Thorough. Got it backwards it seems.

in the book it doesnt have the exponent it just says a2 but maybe its typo? omg >< i will retry

bronxsystem · 2014-01-21 05:15:41

im sure its a typo because the 2 is after the a which does not conform with previous exercises.

i spent 2 hours on this :*( 2 hours 20 minutes

thanks all for help and very sorry for wasting everyones time.

If you follow Post #4 will get you there very easily.

But you will then notice that the book problem must be a typo. But if it is not then the answer is

bronxsystem · 2014-01-21 05:40:01

the answer in book was in line with the typo

but thank you (: i will save this thread and review the problem assuming it was a2 and try work it out using your working (:

thanks thanks thanks

Hi;

Yes, that is more likely to be the problem. Review what has posted up above to get that answer.
