El profesor se sorprenderá mucho al ver tu solución correcta😉
(x - 3)*(x - 2) 2*(x - 4)*(x - 2) 5*(x - 4)*(x - 3) --------------- + ----------------- + ----------------- = 0 4 -3 12
(1*(x-3)*(x-2)/((1-2)*(1-5)))+(2*(x-4)*(x-2)/((2-1)*(2-5)))+(5*(x-4)*(x-3)/((5-1)*(5-2))) = 0
- 23/6 - 5*x^2/12 + 11*x/4 + ((5*(x - 4))*(x - 3))/12 = 0
- 23/6 - 5*x^2/12 + 11*x/4 + 5 - 35*x/12 + 5*x^2/12 = 0
7/6 - x/6 = 0
x = -7/6 / (-1/6)
