Respuesta:
(x²/4)-1=0
x²-4=0
(x+2)(x-2)=0
x+2=0
x=-2
x-2=0
x=2
Solución !
[tex] \frac{ {x}^{2} }{4} - 1 = 0[/tex]
[tex] \frac{ {x}^{2} }{4} = 0 + 1[/tex]
[tex] \frac{ {x}^{2} }{4} = 1[/tex]
[tex] {x}^{2} = 1 \times 4[/tex]
[tex] {x}^{2} = 4[/tex]
[tex] \sqrt{ {x}^{2} } = \sqrt{4} [/tex]
[tex] |x| = 2[/tex]
X1 = 2
X2 = -2
