Question

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

Answer 1

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!

Answer 2

Answer:

±9

Step-by-step explanation:

We are given the equation:

x² - 11 = 70

Solving for x:

x² - 11 = 70

x² = 81                                                          [adding 11 on both sides]

x = ±√81                                                 [taking the square root of both sides]

x = ±9
