" (iii) "(x-1)/(2x+1)+(2x+1)/(x-1)=(5)/(2)

Solve by factorization: (x-1)/(2x+1)+(2x+1)/(x-1)=(5)/(2),quad x!=-(1)/(2),1

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

(x-1) / (2x + 1) + (2x + 1) / (x-1) = (5) / (2), x! =-(1) / (2), 1

Solve by factorization: (x-1)/(2x+1)+(2x+1)/(x-1)=5/2,\ \ x!=-1/2,\ 1

((2x-1)/((x-1)(2x+3))=(1)/(5(x-1))+(k)/(5(2x+3))rArr k=

(2x-1)/((x-1)(2x+3))=1/(5(x-1))-k/(5(2x+3)) , then k =

(1) / (2x-3) + (1) / (x-5) = 1 (1) / (9)

(x^(2)-(x+1)(x+2))/(5x+1)=6

The expression (1)/(1+(x)/(1-(x)/(x+2)))div ((1)/(1-x)+(1)/(1+x))/((1)/(1-x)-(1)/(1+x)) (a) (2x)/(x^(2)+2x+2) (b) (2x)/(x^(2)-1) (c) 1 (d) x^(2)-1

Prove that :log_(e)((x+1)/(x))=2[(1)/((2x+1))+(1)/(3(2x+1)^(3))+(1)/(5(2x+1)^(5))+...]
