Simplify formula by removing bunch of constants.

Hi folks,

I have two formulas, they have a lot of constants in them. How can I change them into one constant?

here is what I have so far:

vecA - VecB
----------------- * 0.012 * ( 1.2 - ( p * 0.4 ) ) = Answer
|vecA - VecB|


Now I have been able to do the last part:

0.012*1.2 - 0.012(p*0.4) correct?
0.0144 - (0.012 * p * 0.4) correct?
0.0144 - (p * 0,004 correct?

so now I have only two constants instead of 3.
Can I even reduce this to 1 constant? how do i do that?


But I have also a somewhat complexer formula:

(vecA - vecB) * 0.8 * (1-|vecC|)
-------------------------------------- = answer
1.2 - ( p * 0.4 )


With this function I can't even get it to two :s
One is considered not a constant so If i could do:

0.8 * (vecA - vecB) * (1-|vecC|)
--------------------------------------- = answer
(1.2 * 1) - (p * 0.4)


If I can get that 1.2 in this fashion:

1.2 * (rest, so 1, p, 0.4 with some formula)

then I can do

0.8 (vecA - vecB) * (1-|vecC|)
--- * ----------------------------------- -> 0.8/1.2 will be one constant again
1.2 rest(1,p,0.4)




Okay so can anyone help me with the first formula and can anyone help me with the second formula?

In the first example, you need two constants, but one can be an integer: 0.0048*(3 - p).

In the second example,
      0.8             2
------------- = ------- .
1.2 - p*0.4     3 - p
