Question

6x ao quadrado - 4x = 0

Answer 1

6x²-4x=0

A=6
B= -4
C=0

Δ=b²-4ac
Δ=4²-4*6*(0)
Δ=16-24(0)
Δ=16-0
Δ=16

x= -b±√Δ/2.a
x= -(-4)±√16/2.6
x=4±4/12

x¹=$\frac{8}{12}$ Simplificando=$\frac{2}{3}$

x²=0

S{ 2/3 e 0 )

Espero ter ajudado!

Answer 2

6x^2-4x=0
2x (3x-2)=0
x (3x-2)=0

x=0
3x-2=0
x=2/3

x1=0, x2=2/3
