## An Alternative Way to Write Fermat's Equation

**Authors:** Chris Sloane

We discovered a way to write the equation x^n+y^n-z^n=0 first studied by Fermat, in powers of 3 other variables defined as; the sum t = x+y-z, the product (xyz) and another term r = x^2+yz-xt-t^2. Once x^n+y^n-z^n is written in powers of t, r and (xyz) we found that 3 cases of a prime factor q of x^2+yz divided t. We realized that from this alternative form of Fermat’s equation if all cases of q divided t that this would lead to a contradiction and solve Fermat’s Last Theorem. Intrigued by this, we then discover that the fourth case, q=3sp+1 also divides t when using a lemma that uniquely defines an aspect of Fermat’s equation resulting in the following theorem:
If x^p +y^p -z^p =0 and suppose x,y,z are pairwise co- prime then any prime factor q of (x^2 +yz) will divide t ,where t= x+y-z
