Did you intend three variables?

Re: Solve Algebra

No. Its a Typo
x and a are the only variables

(-2/(a)^1/2).(x+a)^3/2 = (x+a)^1/2 leads to x = -a - (a^(1/2))/2.

Re: Solve Algebra

I don't think you fully understood my question.

I would like to solve (-2/(a^1/2)).(x+a)^3/2

to get

(x+a)^1/2

Re: Solve Algebra

Well then, ask your question properly.

You should be asking WHEN does (-2/(a^1/2)).(x+a)^3/2 = (x+a)^1/2

And that happens when a = -x

Would be nice if you used * for multiplication and bracket powers, like a^(1/2);
a^1/2 means a divided by 2.

Re: Solve Algebra

Hello, hatchelhoff!

Please check the statement of the problem.
As written, it makes no sense.

And skipjack did answer your question.

Now you use the word "solve".
This means that we have an equation.[color=beige] .[/color](Where?)




Sorry, it can't be done.

Although I could have added "or x = -a" to my previous post, your original request seems to be incorrectly formed from some related problem you were working on (but didn't post).

Re: Solve Algebra

Thanks skipjack apologies for not realising that you had indeed answered the question I posed. I will try to create more accurate posts the next time.
Thanks also sorban for explaining the error of my ways.
Thanks Denis for highlighting that I could have posed my question better.
