factor (a^2-a) = ?

- Nnesha

and change division to multiplication ( multiply top with the reciprocal of the divisor )
\[\large\rm \frac{ a }{ b } \div \frac{ c }{ d } = \frac{ a }{ b } \times \frac{ d }{ c}\]

I have a really, really hard time with the parentheses in these problems. Do they change operations at all?

- Nnesha

parentheses those are factor form of quadratic equation

- TheYankee

I know, but once it is factored, I have a problem using them in division problems. I'm working on the problem and I'm almost done. Would you check my answer when I'm done?

- Nnesha

sure!

- TheYankee

Is this it?

(I'm so bad at these ^^;)

- Nnesha

how did you get that ?

- Nnesha

:-)

- TheYankee

After switching around everything I had (A-4)(a+3)/2(a=3) times (a+3)(a-1)/2(a-4). I cross multiplied 2(a-4) and (a-4)(a=3) to get (a+3)^2 and cross multiplied the other values to get 2(a-1) Then distributed.

- Nnesha

so (a-4)(a+3) = (a+3)^2 ?

- TheYankee

That's what I got when I multiplied it by 2(a-4) The a-4s cancelled out and that left 2 and a+3. I suppose it could have been 2(a+3,) though.

- Nnesha

mhm i'm confused

- Nnesha

i just want to know how u got (a+3)^2 ?? :-)

- Nnesha

yep right (a-4)s cancels out :-)

- TheYankee

I multiplied the value (a-4)(a+3) by 2(a-4). When the a-4s cancelled, I was left with 2 on one side and a+3 on the other. So, re-evaluating, it wouldn't be (a+3)^2 it would be 2(a+3)

- TheYankee

I'm might also make a few errors as I'm under a bit of pressure. My test it timing out :(

- TheYankee

*is

- Nnesha

mhm you got it right *i guess* :|

- TheYankee

So this is the correct answer?

i'm sorry but i'm not allowed to help you 'n ur test
that is for you!

- TheYankee

I'm not cheating :( I'm just trying to confirm what I think is right before my test times out. I am trying!

- TheYankee

It's an openbook.

- TheYankee

If it wasn't open book, I wouldn't ask :( I just have a really hard time understanding.

- TheYankee

But if you don't agree, I understand. Thanks anyway :(

- Nnesha

openbook ) it's not gonna give u the direct answer
i'm pretty sure example that is on ur notebook are different from the test

- Nnesha

:-) gO_Od luck!
