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 = $-frac{sqrt{21} }{3}$
