Aidez moi svpp il faut factoriser les expressions Merciii d’avance!!

A=6^2-5^2x^2
A=(6-5x)(6+5x)
B=10^2+10*3x*2+3^2x^2
B=(10+3x)^2
C=2i)i +1+2+i)=2i(2i+3)
D=b^2-2*b*5+5^2=(b-5)^2

Bonsoir,

Voici ce que je te propose comme factorisation pour les expressions...

E = (2-x)² + (2 -x)(9+x)
E = 4 -4x+x² +18 +2x -9x-x²
E = 22 - 11x
E = 11(2 - x)

F = (5x + 1)² - 81
F = 25x +10x +1 - 81
F = 25x +10x -80
F = (5x - 8)(5x +10)

G = (7d + 2)² - (3d + 4)²
G = (49d² + 28d + 4) - (9d² + 24d +16)
G = 40d² + 4d - 12
G = (4d - 2)(10d + 6)
