Question

6x^2-14=0 помогите срочно!

Answer 1

$6x^{2} - 14 = 0\\6x^{2} = 14\\\\x^{2} = \dfrac{14}{6} = \dfrac{7}{3}\\\\x = \pm \sqrt{\dfrac{7}{3}}$

Answer 2

$6x^{2} -14=0$

$3x^{2} -7=0$

$3x^{2} =7$

$x^{2} =\frac{7}{3}$

x₁ =  $\frac{\sqrt{7} }{3}$ = $\frac{\sqrt{21} }{3}$

x₂ = $-\frac{\sqrt{21} }{3}$

Ответ:  x₁ =   $\frac{\sqrt{21} }{3}$  x₂ = $-\frac{\sqrt{21} }{3}$
