Answer:

[tex]3\sqrt{6}[/tex]  and  [tex]-3\sqrt{6}[/tex]

Step-by-step explanation:

We will take numbers to one side and variables to one side eliminate the "Square" with "Square Root" and solve for the variable x. The process is shown below:

[tex]3x^2-10=152\\3x^2=152+10\\3x^2=162\\x^2=\frac{162}{3}\\x^2=54\\x=\sqrt{54}[/tex]

Now, we need to reduce the radical by using the rule shown below:

[tex]\sqrt{x*y}=\sqrt{x}  \sqrt{y}[/tex]

Now,

[tex]\sqrt{54}=\sqrt{6*9} =\sqrt{6}  \sqrt{9} =3\sqrt{6}[/tex]

The correct answer is  [tex]3\sqrt{6}[/tex] and [tex]-3\sqrt{6}[/tex]

Note: squaring positive and negative makes the same answer
