How to factor the trinomial :

x y - x + y - 1

https://math.stackexchange.com/questions/1811972/how-to-factor-the-trinomial-xy-xy-1

x y - x + y - 1 = x \cdot (y - 1) + 1 \cdot (y - 1) = (x + 1) (y - 1)

x y - x + y - 1 = x y + y - x - 1 = (x + 1) \cdot y + (x + 1) \cdot - 1 = (x + 1) (y - 1)

Three Diophantine equations in three variables, finding

x + y + z

https://math.stackexchange.com/q/1932703

Add the first and second equations together:

13 x - 7 y - z = 0

z = 13 x - 7 y

Now substitute back into the first equation to eliminate

z

9 x + y - 8 (13 x - 7 y) = 0

- 95 x + 57 y = 0

3 y = 5 x

Since all variables ...

Copiato negli Appunti

x\left(y-1\right)+y-1

Esegui il raggruppamento xy-x+y-1=\left(xy-x\right)+\left(y-1\right) e Scomponi x in xy-x.

\left(y-1\right)\left(x+1\right)

Fattorizza il termine comune y-1 tramite la proprietà distributiva.
