/ 2 \ x*(x - 1) 2*\x + 1/ (x - 1)*(x + 2) --------- - ---------- = --------------- 7 28 14
(x*(x-1))/(7)-(2*(x^2+1))/(28) = ((x-1)*(x+2))/(14)
- x/7 + x^2/7 - 2*(x^2 + 1)/28 = ((x-1)*(x+2))/(14)
- x/7 + x^2/7 - 1/14 - x^2/14 = ((x-1)*(x+2))/(14)
(x*(x-1))/(7)-(2*(x^2+1))/(28) = -1/7 + x/14 + x^2/14
1/14 - 3*x/14 = 0
x = -1/14 / (-3/14)
