P = 4x^2 + 5x + 8 + 6x + 2x^2 + 4
P = 4x^2 + 2x^2 + 5x + 6x + 8 + 4
P = 6x^2 + 11x + 12
Q = -9x^2 + 10 - 7x - 13 + 3x^2 + 10x
Q = -9x^2 + 3x^2 - 7x + 10x - 13 + 10
Q = -6x^2 + 3x - 3
R = -4x^2 + 5x - 2x^2 + 6 - 14x + 8
R = -4x^2 - 2x^2 + 5x - 14x + 6 + 8
R = -6x^2 - 9x + 14
S = -3x - 8 - 7x^2 - 9x - 7x - 2
S = -7x^2 -3x - 9x - 7x - 8 - 2
S = -7x^2 - 19x - 10
