bonjour
E=5(3x+7)
E = 5 * 3x + 5 * 7
E = 15x + 35
F=-11(4x-3)
F = -11 * 4x - 11 * (-3)
F = -44x + 33
G=-5/3(x-6)
G = -5/3 * x - 5/3 * (-6)
G = -5x/3 + 6/3 * 5
G = -5x/3 + 2 * 5
G = -5x/3 + 10
H=9-2(3/2x-1)
H = 9 - 2 * 3/2 x - 2 * (-1)
H = 9 - 3x + 2
H = -3x + 11
M=(5+x)(x+7)
M = 5 * x + 5 * 7 + x * x + x * 7
M = 5x + 35 + x^2 + 7x
M = x^2 + 12x + 35
N=(-2/5x-1)(x-4)
N = -2/5 x * x - 2/5 x * (-4) - 1 * x - 1 * (-4)
N = -2x^2/5 + 8x/5 - x + 4
N = -2x^2/5 + 8x/5 - 5x/5 + 4
N = -2x^2/5 + 3x/5 + 4
