P(x) - U(x) = (4x ^ 2 - 1) - (x ^ 2 + 2) = 4x ^ 2 - 1 - x ^ 2 - 2 = 3x ^ 2 - 3P(x) + R(x) = (4x ^ 2 - 1) + (6x ^ 2 + x + 1) = 4x ^ 2 - 1 + 6x ^ 2 + x + 1 = 10x ^ 2 + xS(x) + T(x) + U(x) = (1 / 2x ^ 2 + 4) + (3 / 2x ^ 2 + 5) + (2x ^ 2 + 2) = 1 / 2x ^ 2 + 4 + 3 / 2x ^ 2 + 5 + 2x ^ 2 + 2 = 4x ^ 2 + 11P(x) + 2Q(x) - R(x) = (4x ^ 2 - 1) + (2(1 / 2x ^ 2 + 4)) - (6x ^ 2 + x + 1) = 4x ^ 2 - 1 + x ^ 2 + 8 - 6x ^ 2 - x - 1 = - x ^ 2 - x + 6Q(x) + R(x) - P(x) = (1 / 2x ^ 2 + 4) + (6x ^ 2 + x + 1) - (4x ^ 2 - 1) = 1 / 2x ^ 2 + 4 + 6x ^ 2 + x + 1 - 4x ^ 2 + 1 = \ frac{1}{4x ^ 2 + x + 6}.
