Question
24 Factoriser les expressions suivantes :
x Ab) = x2 + 2x + 1; B(x) = 4x2 + 4x + 1
C(x)=x²-x+ 1
4: D(x) = 4x2 - 12x + 9
E(x) = x2 - 49; F(x) = 16 - 4x2
x Ab) = x2 + 2x + 1; B(x) = 4x2 + 4x + 1
C(x)=x²-x+ 1
4: D(x) = 4x2 - 12x + 9
E(x) = x2 - 49; F(x) = 16 - 4x2

1. Réponse Yeji
A= x²+2x+1
A=(x+1) ²
B=4x²+4x+1
B=(2x+1)²
C=x²-x+1
D=4x²-12x+9
D=(2x-3)²
E=x²-49
E=(x-7)(x+7)
F=16-4x²
F=4(2-x)(2+x)
