El profesor se sorprenderá mucho al ver tu solución correcta😉
2 2 (x - 2) 2*x - 3 (x - 1)*(x + 1) -------- + -------- = --------------- 5 15 3
(x-2)^2/(5)+(2*x^2-3)/(15) = (x-1)*(x+1)/(3)
4/5 - 4*x/5 + x^2/5 + (2*x^2 - 3)/15 = (x-1)*(x+1)/(3)
4/5 - 4*x/5 + x^2/5 + - 1/5 + 2*x^2/15 = (x-1)*(x+1)/(3)
(x-2)^2/(5)+(2*x^2-3)/(15) = -1/3 + x^2/3
14/15 - 4*x/5 = 0
x = -14/15 / (-4/5)
