Bonjour,
Factoriser:
I=4x²+40x+100+(2x+10)(x-1)
I= 4(x²+10x+25)+2(x+5)(x-1)
I= 4(x+5)(x+5)+2(x+5)(x-1)
I= (x+5)(4(x+5)+2(x-1))
I= (x+5)(4x+20+2x-2)
I= (x+5)(6x+18)
I= 6(x+5)(x+3)
J=-27a³ - 36a²- 9a
J= -9a(3a²+4a+1)
J= -9a(( 3a²+3a+a+1)
J= -9a(3a(a+1)+(a+1))
J= -9a(a+1)(3a+1)
K=2x²- 12x+18-(x-3)(2x+4)
K= 2(x²-6x+9)-(x-3)(2x+4)
K= 2(x-3)(x-3)-(x-3)(2x+4)
K= (x-3)(2(x-3)-(2x+4))
K= (x-3)(2x-6-2x-4)
K= (x-3)(-10)
K= -10(x-3)
L=x²-25+4 (x²+10x+5)
A toi de factoriser, maintenant.
