This is my first contribution and I hope you find it useful.
2 pieces of free software:
1- PrimeFactorizor : Give you prime factorization of any number from 1-999983.
When it works for the first time, it will make a primes.txt to make the next calculations faster so be patient (for the first time only )
It's a fast program to solve quadratic equations using the common Quadratic Formula.
I compressed the two programs individually in two zips files but each file has the size more than accepted.
How can I upload them?
