Bonsoir,
Exercice 1 :
A = [tex]x^{2} - 9[/tex]
B = [tex]9x^{2} - 6\sqrt{2}x + 2[/tex]
C = [tex]16x^{2} -49[/tex]
D = [tex]18x^{2} -21x -4[/tex]
E = [tex]\sqrt{6}x^{2} + x - \sqrt{6}[/tex]
F = [tex]x^{2} +2x +1[/tex]
Exercice 2 :
A = [tex](x - 3)(x + 3)[/tex]
B = [tex](3x - 7)^{2}[/tex]
C = [tex](3x + 5)^{2}[/tex]
D = [tex](x - 4)(3x + 2)[/tex]
E = [tex]5(3x - 5)(x + 4)[/tex]
F = [tex]2(\sqrt{3} - x)(8 + 3x)[/tex]
Bonne soirée
