(x - 1)(x + 3) = (x + 2)(x - 3) + 1?
(x - 1)(x + 3) = (x + 2)(x - 3) + 1.

(x - 1)(x + 3) = (x + 2)(x - 3) + 1.
En resumen
(x - 1)(x + 3) = (x + 2)(x - 3) + 1 x² + 2x - 3 = x² - x - 6 + 1 x² + 2x - x² + x = - 6 + 1 + 3 3x = - 2 x = - 2 / 3.

(x - 1)(x + 3) = (x + 2)(x - 3) + 1
x² + 2x - 3 = x² - x - 6 + 1
x² + 2x - x² + x = - 6 + 1 + 3
3x = - 2
x = - 2 / 3.

Aqui esta el proceso :
x - 1 + x + 3 = x + 2 + x - 3 + 1
2x + 2 = 2x
2x - 2x = - 2
0x = - 2.
