(x-6)/(x+8) x (x+4)/(x-6) = (x+4)/(x+8)
(x+4)/(x-6) : (x-6)/(x+12) = (x+4)/(x-6) x (x-6)/(x+12) = (x+4)/(x+12)
3x-2≠0 ⇒x≠2/3
(x^2-2)/(3x-1) pt x=-3⇒(9 - 2)/(-9-1) = - 7/10
3x/(x-3) x (x+3)/(x+3) = 3x(x+3)/(x^2 - 9)

3x-2 ≠0 ⇒ x ≠ 2/3
(4+3)/(-4-1)=-7/5
2x/(x+2) x (x-2)/(x-2) = 2x(x-2)/(x^2-4)
(x-3)(x+3)/(x+3)^2 = (x-3)/(x+3)
1/(x+1) + 2/(x+3) = (x+3+2x+2)/(x+2)(x+3) = (3x+5)/(x+2)(x+3)

(2x+6+x+2)/(x+2)(x+3) = (3x+8)/(x+2)(x+3)
(x+2)/(x+4)
(x-3)/(x-4) : (x-3)/(x-5) = (x-3)/(x-4) x (x-5)/(x-3) = (x-5)/(x-4)

x≠2/3
(4+3)/(-4-1) = - 7/5
2x/(x+2) x (x-2)/(x-2) = (2x^2-4x)/(x^2-4)
(x-3)(x+3)/(x+3)^2 = (x-3)/(x+3)
s-a facut mai sus

2/(x+2) + 1/(x+3) = (2x+6+x+2)/(x+2)(x+3) = (3x+8)/(x+2)(x+3)
(x+2)/(x+4)
(x-3)/(x-4) : (x-3)/(x-5) = (x-3)/(x-4) x (x-5)/(x-3)=(x-5)/(x-4)
verifica si tu si corecteaza daca e cazu
