X^2- 11 = 70 I need help on how to solve this

brilliants [131]

Answer: Add 11 to the other side of the equation, giving you 81. Then, since x is square you are going to need to square root both sides ( $\sqrt{x}$ this symbol). When you do that, you should get what x is! Let me know if you still need help!
