Question

(x-3)(x+2)=0
rezolvare in multimea nr rationale plzzz

Answer 1

$\bf (x-3)(x+2)=0$

$\bf x-3=0 \Rightarrow \boxed{\bf x_{1} = 3}$

$\bf x+2=0 \Rightarrow \boxed{\bf x_{2} = -2}$

$\bf x\in (-2,3)$

Answer 2

Răspuns:

x = 3 sau x = -2

Explicație pas cu pas:

Daca (x - 3)(x + 2) = 0 atunci fie x - 3 = 0, fie x + 2 = 0.

x - 3 = 0 => x = 3

x + 2 = 0 => x = -2

Succes!
