Question

Resuelve mentalmente :

a) (x-3)'2 = 0

b) ( x +7) (x - 5 )= 0

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

d) 5( x'2- 6 ) ' 2 = 0

Answer 1

Respuesta:

Hola espero que entiendas ✌️

a) (x-3)'2 = 0

X - 3 = 0

X = 3

b) ( x +7) (x - 5 )= 0

X + 7 = 0 ^ x - 5 = 0

X = - 7 ^ x = - 5

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

2x = 0 ^ x + 3 = 0 ^ x - 2 =0

X = 0 ^ x = - 3 ^ x = 2

d) 5( x'2- 6 ) ' 2 = 0

X² - 6 = 0

(x + ¬/6)(x - ¬/6) =0

X = - ¬/6 ^ x = ¬/6
