Explications étape par étape
Bonsoir
F = 64-( x-8)2
F = 8^2 - (x - 8)^2
F= (8 - x + 8)(8 + x - 8)
F = (16 - x)x
F = x(16 - x)
G = (2x-3)2-(7 x-4)2
G = (2x - 3 - 7x + 4)(2x - 3 + 7x - 4)
G = (-5x + 1)(9x - 7)
H = 9(x-2)2-(X+3)2
H = 3^2(x - 2)^2 - (x + 3)^2
H = [3(x - 2 - x - 3)][3(x - 2 + x + 3)]
H = (3x - 6 - 3x - 9)(3x - 6 + 3x + 9)
H = (-15)(6x + 3)
