Bonjour j'ai besion d'aide pour mes exercices de math svp développer et reduire les expressions suivantes. g(x)=(3x-2)²-3(x+2)(4x-3) h(x)=((x/3)-(3/2))(2x+(1/3) I(x)=(x+5)(x-5)+3(x+1)² factoriser les expressions suivante : k(x)=(2x+1)(3x-2)-3(2x+1)(-x+1) l(x)=2(4x+5)(3x+7)+(3x+7(2x-5) M(x)=(2x+3)²-(x+1)² N(x)=16(x-1)²-(2x-45)² merci

Bonsoirg(x)=(3x-2)²-3(x+2)(4x-3)
g(x) = 9 x² - 12 x + 4 - 3 ( 4 x² - 3 x + 8 x - 6)
g(x) = 9 x² - 12 x + 4 - 12 x² + 9 x - 24 x + 18
g(x) = - 3 x² - 9 x + 22
h(x)=((x/3)-(3/2))(2x+(1/3)
h(x) = (2 x /6 - 9/6) ( 6 x /3 + 1/3)
h(x) = ( 2 x - 9) ( 6x +1)
h(x) = 12 x² + 2 x - 54 x -9 = 12 x² - 52 x -9
I(x)=(x+5)(x-5)+3(x+1)²
i(x) = x² - 25 + 3 ( x² + 2 x +1)
i(x) = x² - 25 + 3 x² + 6 x + 3
i(x) = 4 x² + 6 x - 22
factoriser les expressions suivante :
k(x)=(2x+1)(3x-2)-3(2x+1)(-x+1)
k(x) = (2 x +1) ( 3 x -2 ) - 3 ( - x +1)
k(x) = (2 x +1) ( 3 x - 2 + 3 x - 3)
k(x) = (2 x +1) ( 6 x - 5)
l(x)=2(4x+5)(3x+7)+(3x+7(2x-5)
i(x) = ( 3 x +7) ( 8 x + 10 + 2 x -5)
i(x) = ( 3 x +7) ( 10 x +5)
M(x)=(2x+3)²-(x+1)²
m(x) = ( 2 x + 3 + x +1) ( 2 x +3 - x -1)
m(x) = ( 3 x +4)(x +2)
