(x + 1)(2x + 5) = (2x + 3)(x - 4 + 5).
En resumen
2x ^ + 5x + 2x + 5 = 2x + 3)(x + 1) 2x ^ + 7x + 5 = 2x ^ + 2x + 3x + 3 2x ^ - 2x ^ + 7x + 5 = 5x + 3 7x + 5 = 5x + 3 7x - 5x = 3 - 5 2x = - 2 X = - 2 / 2 X = - 1.

2x ^ + 5x + 2x + 5 = 2x + 3)(x + 1)
2x ^ + 7x + 5 = 2x ^ + 2x + 3x + 3
2x ^ - 2x ^ + 7x + 5 = 5x + 3
7x + 5 = 5x + 3
7x - 5x = 3 - 5
2x = - 2
X = - 2 / 2
X = - 1.
