Ex 2:

 

Factoriser les expressions suivantes:

 

E=4x²-16³                                  F=3(2x+1)-4x(2x+1)

Sagot :

E = 4x² - 16³  

E = 4(x² - 4³)

 

F = 3(2x + 1) - 4x(2x + 1)

F = (2x - 1)(3 - 4x)

JUSTYOUNG

E=4x²-16³

= 4 * x² - 4 *4⁵

=4(x²-1024)

 

F=3(2x+1)-4x(2x+1)

=(2x+1)(3-4x)
