bonsoir je dois Factoriser les expressions suivantes.
A=40+4t
B=7Z+97
C=3y² + 2y
D= 4x(x + 2) + 3(x + 2)
E=-3y(y + 6) + 7(y + 6)
F = (x - 1)(5x + 4) + (3 + x)(x - 1)​

Bonsoir,

Explications étape par étape

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

B = (t-3)2-t(t-3) = (t-3)(2-t)

C = (5x-4)(3x+1)+(2-x)(5x-4) = (5x-4)[(3x+1)+(2-x)] = (5x-4)(2x+3)

D = 2y(8y-3)-(3-2y)(8y-3) = (8y-3)[2y-(3-2y)] = (8y-3)(4y-3)
