Hey Lovechild and everyone. I can&#039;t even do simple algebra. When the time comes what should i do for nagitive exponents?? And square roots raise to a power??

2. ## Re:Help with Algebra??

okay step one

We extend both divisions by one (formed as the divisor of the other division - 5x / 5x is one as is x / x)

2 * 5x 3(x-1) * x
-------- + ------------- = 1
x * 5x 5x * x

Now we can collect these into one division

2 * 5x + 3(x-1) * x
------------------------ = 1
5x*x

And clean it up a bit

10x + 3x2 - 3x
---------------------------- = 1
5x2

Now multiple both sides by 5x2

10x + 3x2 - 3x = 5x2

And divide both sides by x

10 + 3x - 3 = 5x

clean up a bit

3x + 7 = 5x

substract 3x from both sides

7 = 2x

switch the sides

2x = 7

divide by 2

7
x = ----- = 3.5
2

One step at the time, let&#039;s get the algebra down first then we can work on the more advanced stuff later..

I would really look around for a tutor if I was you, a few hours in person training can do wonders, especially for brushing up on basic stuff like algebra and other common concepts.

I&#039;m happy to help but doing this over the internet is really not that easy.

If you ask me i&#039;m kind of cheating by writing down what you told me just now. I don&#039;t have a clue. Can we try a different and easier method with less confused?? Please reply back.

I&#039;m not much for using another method - I would rather explain to you why this is good, it&#039;s good because it works every time and it&#039;s absolutely straightforward once you get a hang of it, don&#039;t worry it took me a while also.

What specifically don&#039;t you understand.

Lovechild. Would it be easier if you made a long distance call and do it over phone??

You want ME to call you overseas, and fork over the phone bill as well - now you are pushing it buddy.

yeah thats it. What i don&#039;t understand is everything. I told you what i did and i guess i did it wrong.

Okay, here are the basics.

You can extend a division by 1 without it changing the value of the division.

Here we use that to turn two divisions into one.

since:

1 can be written as fx.

1 5x
--- or ---
1 5x

Now multiplication of a fraction with another faction is simple

just multiple directly like this:

2 4 2 * 4 8
--- * --- = ------ = ---
3 2 3 * 2 6

Now we use this to extend all divisions in the problem by one - since that doesn&#039;t alter the value of the total equation it&#039;s perfectly legal.

Now we want to get one division so we extend by one using

exsample:

1 1
--- + ---
2x 3x

because:

2x
---- = 1
2x

Freely extend the other division but this - following the prior rule:

1 1 * 2x
--- + -------
2x 3x * 2x

Now we do the same to the other division, but here we of course use the other division to pick our constant.

1 * 3x 1* 2x
-------- + ---------
2x * 3x 3x * 2x

The point here is getting the same in this section

x
---
y &lt;=== HERE

because then they have a common divisor and thus we are allowed to do this

1 * 3x + 1* 2x
------------------
2x * 3x

This has the same value still.

Now we can clean up a bit

3x + 2x
----------
6x 2

And now we have a single division with which to continue calculations.

I understand that just a little. Well anyway i also know 8

can be reduce to
