Question
A= 4r + 4t
B= 7z+9z
C= 3y puissance2+2y
D= 4x(x+2)+3(x+2)
E= -3y(y+6)+7(y+6)
F= (x-1)(5x+4)+(3+x)(x-1)
B= 7z+9z
C= 3y puissance2+2y
D= 4x(x+2)+3(x+2)
E= -3y(y+6)+7(y+6)
F= (x-1)(5x+4)+(3+x)(x-1)

Réponse:
A= 4r+4t
=4(r+t)
B= 7z+9z
= z(7+9)
D=4x(x+2)+3(x+2)
= (x+2)(4x+3)
= 4x²+3x+8x+6
= 4x²+11x+6
E= -3y(y+6)+7(y+6)
= (y+6)(-3y+7)
= -3y²+7y-18y+42
= -3y²-11y+42
F= (x-1)(5x+4)+(3+x)(x-1)
= (x-1)(5x+4+3+x)
= (x-1)(6x+7)
= 6x²+7x-6x-7
= 6x²+x-7
