El profesor se sorprenderá mucho al ver tu solución correcta😉
(4*x - 1)*(x + 7/2) (2*x + 1)*(x - 21/2) ------------------- - -------------------- = 75/2 4 2
((4*x-1)*(x+(7/2))/4)-((2*x+1)*(x-(21/2))/2) = (75/2)
- 7/8 + x^2 + 13*x/4 - (2*x + 1)*(x - 21/2)/2 = (75/2)
- 7/8 + x^2 + 13*x/4 + 21/4 - x^2 + 10*x = (75/2)
-265/8 + 53*x/4 = 0
x = 265/8 / (53/4)
