Question

Bom pfff resolva pelo o DELTA

X²-4x=0

-4x²=0

Answer 1

Bom dia

Δ= b²-4.a.c

x²-4x=0
Δ= (-4)²-4*1*0
Δ= 16

-4x²
Δ= 0²-4.(-4).0
Δ=0

Answer 2

X²-4x=0
a=1 b=-4 c=0

Δ=b²-4ac
Δ=(-4)²-4.1.0
Δ=16-4.0
Δ=16

X=-b±√Δ/2a
X=-(-4)±√16/2.1
X=4±4/2
X'=4+4/2=8/2=4
X"=4-4/2=0/2=0


-4x²=0
a=-4 b=0 c=0

Δ=b²-4ac
Δ=0²-4.(-4).0
Δ=0+16.0
Δ=0

X=-b±√Δ/2a
X=-0±√0/2.(-4)
X=-0±0/-8
X'=-0+0/-8=0/-8=0
X"=-0-0/-8=0/-8=0



Espero ter ajudado :-)
