OK.. this is an easy one for all the programmers out there but I don't know hell to do it.
I have this bunch of excersises I need to make. They all consist of the same format:
a are filled in by a number and so are b and c. You have to see what X is and that are mostly two solutions.
You first have to make some calculations:
D= b²- 4.a.c
If D is negative there is no solution.
Now you calculate X:
X1= (-b+VD) : 2.a (V is a square root (or how 'd you call it e.g. V9=3)
X2= (-b-VD) : 2.a
Can someone create a program that automates this things. So I only have to fill in the values of a, b and c and I would get the solution? I don't think this is hard to do. Oh well I'l give some 10k button impressions at freesources.net as a reward.
