(d^2+d-30)/(d^2+3d-40) + (d^2+14d+48)/(d^2-2d-48)
= (d - 5)(d + 6)/(d + 8)(d - 5) + (d + 6)(d + 8)/(d - 8)(d + 6)
= (d + 6)/(d + 8) + (d + 8)/(d - 8)
= (d + 6)(d - 8)/(d + 8)(d - 8) + (d + 8)(d + 8)/(d - 8)(d + 8)
= (d^2 - 2d - 48)/(d + 8)(d - 8) + (d^2 + 16d + 64)/(d + 8)(d - 8)
= (2d^2 + 14d + 16)/(d + 8)(d - 8)

x^3 - x^2 + x - 1
= x^2(x - 1) + (x - 1)
= (x - 1)(x^2 + 1);

x^2 - 1 = (x + 1)(x - 1)

The least common multiple of x^3 - x^2 + x - 1 and x^2 - 1 is (x + 1)(x - 1)(x^2 + 1)
