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
  • Nnesha
parentheses those are factor form of quadratic equation
TheYankee
  • 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?

how did you get that ?
Nnesha
  • Nnesha
:-)
TheYankee
  • 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
  • Nnesha
so (a-4)(a+3) = (a+3)^2 ?
TheYankee
  • 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
  • Nnesha
mhm i'm confused
Nnesha
  • Nnesha
i just want to know how u got (a+3)^2 ?? :-)
Nnesha
  • Nnesha
yep right (a-4)s cancels out :-)
TheYankee
  • 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)

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

TheYankee
  • 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
  • TheYankee
If it wasn't open book, I wouldn't ask :( I just have a really hard time understanding.
TheYankee
  • TheYankee
But if you don't agree, I understand. Thanks anyway :(
Nnesha
  • Nnesha
