bonjour
A = 9 x ⁴ + 2 x² + 25
B = 36 x² + 24 x + 4
C = 9 x² - 30 x + 25
D = ( 6 x - 3 ) ( 2 x + 4 ) - 2 ( 6 x - 3 ) ( 5 x + 5 )
d = ( 6 x - 3 ) ( 2 x + 4 - 10 x - 10 )
d = ( 6 x - 3 ) ( - 8 x - 6 )
d = - 2 ( 6 x - 3 ) 4 x + 3 )
E = tu fais pareil tu factorises 12 x + 4 en 4 ( 3 x + 1 )
F = ( 3 x + 5 ) ( x + 8 - 2 x - 9 + 4 x )
F = ( 3 x + 5 ) ( 3 x - 1 )
I = 64 - ( 4 x + 2 )²
I = ( 8 + 4 x + 2 ) ( 8 - 4x - 2 )
i = ( 4 x + 10 ) ( - 4 x + 6 )
I = 4 ( 2 x + 5 ) ( - 2 x + 3 )
J = tu factorises x² + 6 x + 9 en ( x + 3 )²
