Bonsoir
A = (-3x + 5)(2x - 3)
A=-6x²+9x+10x-15
A=-6x²+29x-15
B = (2x - 1)(2x + 1)
I.R B=4x²-1
C = (-2 + x)(x + 4)
C=-2x-8+x²+4x
C=x²+2x-8
D = (4 - 3x)(x - 6)
D=4x-24-3x²+18x
D=-3x²+22x-24
E = (-5x - 2)(3x + 2)
E=-15x²-10x-6x-4
E=-15x²-16x-4
F = (-3 - x)(2x - 7)
F=-6x+21-2x²+7x
F=-2x²+x+21
G = (3x - 5)²
I.R G=9x²-30x+25
