Răspuns:

Explicație pas cu pas:

1.

(5x + 5) / (x^2 - 1) = 5(x+1)/(x - 1)(x + 1) = 5/(x - 1)

____________

3.

5/(x + 6) + x/(x + 6) = (5 + x)/(x + 6)

------

(x - 2)/x + 3/(x + 2) = [(x - 2)(x + 2) + 3x]/x(x + 2) = (x^2 - 4 + 3x)/x(x+2)

------

3/(x^2 - x) - 6/(x^2 - 1) = 3/x(x - 1) - 6/(x + 1)(x - 1) =

[3(x + 1) - 6x(x - 1)]/x(x+1)(x-1) = (3x + 3 - 6x^2 + 6x)/x(x+1)(x-1) =

(-6x^2 + 9x + 3)/x(x+1)(x-1)

2.

(x+4)(x - 4)/5x(x - 4) = (x^2 - 16)/5x(x - 4)

Answer 2

Răspuns:
