Answer:

Step-by-step explanation:

x²-2=2⅔ +2-⅔

x^2 = 2^1 + 2⅔ +2-⅔

x^2 =   4.21736

x = 2.0536.

Plug this into 2x^3 - 6x:

= 2(2.0536)^3 - 6(2.0536)

= 5

So 2x^3 - 6x = 5.

answer:

[tex]x1 = - \sqrt{6} \\ x2 = \sqrt{6} [/tex]

Step-by-step explanation:

[tex]x ^{2} - 2 = \frac{8}{3} + 2 - \frac{2}{3} [/tex]

[tex]x^{2} - 2 = 4[/tex]

[tex]x^{2} = 4 + 2[/tex]

[tex]x^{2} = 6[/tex]

[tex]x = - \sqrt{6} \\ x = \sqrt{6} [/tex]

[tex]x1 = - \sqrt{6} \\ x2 = \sqrt{6} [/tex]
