Bonjour est-ce que c’est possible de me dire si c’est juste svp merci

I = 25xau carre-9+(5x-3)(7×+8)
I = (5x-3)(5×+3)+(5x-3)(7×+8)
I = (5x-3)(5×+3+7×+8)
I = (5x-3)(12×+3+8)
I = (5x-3)(12×+11)

J = 9-48 × + 64xau carré-(18-48 x + 6x-16xau carré)
J = 9 - 48 × + 64xau carré- 18 +48 x - 6 x + 16xau carré
J= 80xau carre-6x-9

K = (10x-5)(10×+5)+2(10×+5)(2x-4)
K = (10×+5)[(10x-5)+2(2x-4)1
K = (10×+5)Г(10x-5)+4x-81
K= (10×+5)10x-5+4x-8)
K = (10×+5)(14x-13)

L = (2x-3)(4x+2)+(4×+2)(7×-8)
L= (4×+2)(2x-3+7×-8)
L = 2(2x+1) (2x-3+7×-8)
L = 2(2x+1) (9x-3-8)
L = 2(2x+1) (9x-11)
