Nous allons factoriser les expressions suivantes :
a. (2x - 1)(3x + 1) + (2x - 1)(5 - 2x)
b. (x - 3)(2x + 2) + (x-3)x
c. 2(x - 1) - (x - 1)(3x + 3)
d. (4x + 3)(2 - 3x) - (2 – 3x)(x - 1)
c. (+ 1)+ (+ 1)(2.r - 3)
(3a - 4)(3 -- 2x) - (3 - 2.)
Svp je comprends rien et c. a rendre

Bonsoir,

Factoriser:

A = (2x - 1)(3x + 1) + (2x - 1)(5 - 2x)

A = (2x - 1)(3x + 1 + (5 - 2x)

A = (2x - 1)(3x + 1 + 5 - 2x)

A = (2x - 1)(x + 6)

B = (x - 3)(2x + 2) + x(x - 3)

B = (x - 3)(2x + 2 + x)

B = (x - 3)(3x + 2)

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

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

C = (x - 1)(2 - 3x - 3)

C = (x - 1)(-3x - 1)

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

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

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

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

E = incompréhensible

F = incompréhensible

Bonne soirée.
