Sagot :
H=(x+8)2-16(x+8)
H=2x+16-16x-128
H=-14x-112
ou
factoriser
H=(x+8)(2-16)
H=-14(x+8)
Coucou!!!
H= (x+8)2 - 16(x+8)
= (2x+16) - (16x+128)
= 2x+16 -16x-128
= 2x-16x + 16 -128
= -14x - 112
Voilou!!! ^^
devoir de maths je bloque H=(x+8)2-16'x+8)
H=(x+8)2-16(x+8)
H=2x+16-16x-128
H=-14x-112
ou
factoriser
H=(x+8)(2-16)
H=-14(x+8)
Coucou!!!
H= (x+8)2 - 16(x+8)
= (2x+16) - (16x+128)
= 2x+16 -16x-128
= 2x-16x + 16 -128
= -14x - 112
Voilou!!! ^^
