5x 4x 5x(x-1)+4x 5x²-5x+4x x(5x-1)
a) ------ + -------------= -------------- = --------------- = --------------
x+1 (x+1)(x-1) (x+1)(x-1) (x+1)(x-1) (x+1)(x-1)

b)---- + ------ - ------ - --- =
4x x + 1 x^2 4
a)
5x 4x 5x(x-1)+4x 5x^2-5x+4x 5x^2-x x(5x-1)
------ + -------------= --------------- = --------------- = -------------- = ------------
x+1 (x+1)(x-1) (x+1)(x-1) (x+1)(x-1) (x+1)(x-1) (x+1)(x-1)
b)
El denominador común es 4x^2(x+1)
5x(x+1)+4x^2-(2x-3)(4)(x+1)-3x^2(x+1) 5x^2+5x+4x^2-8x^2-8x+12x+12-3x^3-3x^2
--------------------------------------------------- = --------------------------------------------------
4x^2(x+1) 4x^2(x+1)
-3x^3-2x^2+9x+12
=-------------------------
4x^2(x+1)
y ya no se puede simplificar más
