Question

x2 – x - 6 = 0, los valores de x son?

Answer 1

x² - x - 6 = 0

(x - 3) (x + 2) = 0

x - 3 = 0 x + 2 = 0

x = 3 x = - 2

R/ Los valores de "x" son - 2 y 3

Verificas la solución

x² - x - 6 = 0

(- 2)² - (- 2) - 6 = 0

4 + 2 - 6 = 0

6 - 6 = 0

0 = 0

x² - x - 6 = 0

(3)² - 3 - 6 = 0

9 - 3 - 6 = 0

9 - 9 = 0

0 = 0
