Bonjour,
J'ai besoin d'aide pour cet exercice.
Factorisez les expressions suivantes :
I = 25x²-9+(5x-3)(7x+8)
J = 9-48x+64x²-(6x+2x)(3-8x)
K = 100x²-25-(20x+10)(2x-4)
L = (2x-3)(4x+2)+(4x+2)(7x-8)
Merci

I = 25x²-9+(5x-3)(7x+8)
I = (5x-3)(5x+3)+(5x-3)(7x+8)
I = (5x-3)(5x+3+7x+8)
I = (5x-3)(12x+3+8)
I = (5x-3)(12x+11)
J = 9-48x+64x²-(6x+2x)(3-8x)
J = (3-8x)²-(6x+2x)(3-8x)
J = (3-8x)²+(-6x-2x)(3-8x)
J = (3-8x)(3-8x-6x-2x)
J = (3-8x)(3-16x)
K = (10x-5)(10x+5)+2(10x+5)(2x-4)
K = (10x+5)[(10x-5)+2(2x-4)]
K = (10x+5)[(10x-5)+4x-8]
K = (10x+5)(10x-5+4x-8)
K = (10x+5)(14x-13)
L = (2x-3)(4x+2)+(4x+2)(7x-8)
L = (4x+2)(2x-3+7x-8)
L = 2(2x+1)(2x-3+7x-8)
L = 2(2x+1)(9x-3-8)
L = 2(2x+1)(9x-11)
Voilà !
