Answer 1

Răspuns:

Explicație pas cu pas:

1) 6x -9 >= 0,  2x >= 3, x >= 3/2

x^2 = 6x -9

x^2 -6x +9 = 0

(x-3)^2 = 0,  x-3 = 0,  x = 3

2) 4x -3 >= 0,  4x >= 3, x >= 3/4

4x -3 = x^2

x^2 -4x +3 = 0

(x-3)(x-1) = 0,  x1 = 1,  x2 = 3, ambele convin

3) 6x + 10 >= 0, 6x >= -10, x >= -10/6 = -5/3

6x +10 = 36

6x = 26,  x = 26/6 = 13/3
