Answer:

x = 8

Step-by-step explanation:

[tex]x^{2}[/tex] - 14 = 50

You first need to add 14 to both sides:

[tex]x^{2}[/tex] - 14 = 50

  + 14   + 14

_________

[tex]x^{2}[/tex] = 64

To get rid of the square, you need to square root both sides:

[tex]x^{2}[/tex] = 64

[tex]\sqrt{x^2} = \sqrt{64}[/tex]

This gives you:

x = 8, as your final answer.
