O.E. = 1/(x+2) + 1/(x+2) + 2x/(x+2)
= (1/x+2) (1 + 1+ 2x)
= (1(x+2))(2 + 2x)
= (2/x+2) + (2x/x+2)
= 2x +2/x+2
= (1/x+2) (1 + 1+ 2x)
= (1(x+2))(2 + 2x)
= (2/x+2) + (2x/x+2)
= 2x +2/x+2

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

(x/x + 2)/(1/x + 1/x + 2)
= (1 + 2)/(2/x + 2)
= 3/(2/x + 2)
= 3x/(2x + 2), where x ≠ -1, x ≠ 0
= (1 + 2)/(2/x + 2)
= 3/(2/x + 2)
= 3x/(2x + 2), where x ≠ -1, x ≠ 0
