A = 5x + 3x - 2 + 5x - x + 3 + 4x
A = 5x + 3x + 5x - x + 4x - 2 + 3
A = 16x + 1
B = 5x + 20y + 4x^2
B = 4x^2 + 5x + 20y
C = 5x + (3x + 4 + 2x - 1)
C = 5x + 3x + 2x + 4 - 1
C = 10x + 3
D = 4x * x + 3x * x - x * x
D = 4x^2 + 3x^2 - x^2
D = 6x^2
E = 2x - (4x + 3)
E = 2x - 4x - 3
E = -2x - 3
F = 5x * 6x + 2x^2 - 4x^2

G = 20x + 4
Developer :
A = 5x(x + 3)
A = 5x * x + 5x * 3
A = 5x^2 + 15x
B = -3x(x + 4)
B = -3x * x - 3x * 4
B = -3x^2 - 12x
C = x(-x + 5)
C = x * (-x) + x * 5
C = -x^2 + 5x
D = 3x(x + 2) + 2
D = 3x * x + 3x * 2 + 2
D = 3x^2 + 6x + 2
E = -x(-x + 2)
E = -x * (-x) - x * 2
E = x^2 - 2x
F = (5x + 3) * 4
F = 5x * 4 + 3 * 4
F = 20x + 12
