RESOLVER LAS SIGUIENS ECUACIONES CUADRATICAS POR FACTORIZACIÓN x2 - 9x + 20 = 0 x2 = 5x + 24 x2 - 10x = 24 x2 = 42 + x x2 - 3x = 40.

Ximena1303 · Accepted Answer

X² - 9x + 20 = (x - 4)(x - 5)

x² - 5x - 24 = 0 (x - 8)(x + 3)

x² - 10x = 24 x² - 10x - 24 = (x - 12)(x + 2)

x² = 42 + x x² - x - 42 = (x - 7)(x + 6)

x² - 3x = 40 x² - 3x - 40 = (x - 8)(x + 5) .

Saijul2003 · Answer

X2 - 9x + 20 = 0

(x - 5) (x - 4)

X = 5.

X = 4

X2 = 5x + 24

X2 - 5x - 24 = 0

(x - 8) (x + 3)

X = 8.

X = - 3

X2 - 10x = 24

X2 - 10x - 24 = 0

(x - 12 ) (x + 2)

X = 12 x = - 2

X2 = 42 + x

X2 - x - 42 = 0

(x - 7)(x + 6)

X = 7 x = - 6

X2 - 3x = 40

X2 - 3x - 40 = 0

(x - 8)(x + 5)

X = 8 x = - 5.
