6x^2=726smiddle" class="latex-formula">
​

Answer 1

Answer:

$x=11$

Step-by-step explanation:

Step 1:  Divide both sides by 6

$6x^2 / 6 = 726 / 6$

$x^2 = 121$

Step 2:  Square root both sides

$\sqrt{x^2} = \sqrt{121}$

$x = 11$

Answer:  $x=11$

Answer 2

Answer:

$6 {x}^{2} = 726 \\ \frac{6 {x}^{2} }{6} = \frac{726}{6} \\ {x}^{2} = 121 \\ x = \sqrt{121} \\ x = 11$
