Ejercicio 127 resuelto del álgebra de Baldor numero 29 x-2/2x2-5x-3 + x-3/2x2-3x-2 + 2x-1/x2-5x+6

Answer 1

(x - 2)/(2x² - 5x - 3) + (x - 3)/(2x² - 3x - 2) + (2x - 1)/(x² - 5x + 6)
(x - 2)/(2x + 1)(x - 3) + (x - 3)/(2x + 1)(x - 2) + (2x - 1)/(x - 3)(x - 2)

i)
((x - 2)(2x + 1)(x - 2) + (x - 3)(2x + 1)(x - 3))/(2x + 1)(x - 2)(2x + 1)(x - 3)
((x - 2) + (x - 3))/(2x + 1)

ii)
((x - 2) + (x - 3))/(2x + 1) + (2x - 1)/(x - 3)(x - 2)
(x - 2)(x - 3)(x - 2) + (x - 3)(x -3)(x - 2) + (2x - 1)(2x + 1))/(2x + 1)(x - 3)(x - 2)
(x - 2) + (x - 3) + (2x + 1)
x - 2 + x - 3 + 2x + 1
4x - 4
