•X² + 5X = - 6•X² = 4X - 3•X² + 6 = 7X?

•X² + 5X = - 6 •X² = 4X - 3 •X² + 6 = 7X.

En resumen

A x² + 5x = - 6 x² + 5x + 6 = 0 (x + 3)(x + 2) = 0 x + 3 = 0 x + 2 = 0 x = - 3 x = - 2 b x² = 4x - 3 x² - 4x + 3 = 0 (x - 3)(x - 1) = 0 x - 3 = 0 x - 1 = 0 x = 3 x = 1 c x² + 6 = 7x x² - 7x + 6 = 0 (x - 6)(x - 1) = 0 x - 6 = 0 x - 1 = 0 x = 6 x = 1.

A x² + 5x = - 6

x² + 5x + 6 = 0

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

x + 3 = 0 x + 2 = 0

x = - 3 x = - 2

b x² = 4x - 3

x² - 4x + 3 = 0

(x - 3)(x - 1) = 0

x - 3 = 0 x - 1 = 0

x = 3 x = 1

c x² + 6 = 7x

x² - 7x + 6 = 0

(x - 6)(x - 1) = 0

x - 6 = 0 x - 1 = 0

x = 6 x = 1.
