Question

Use the square root property to solve x^2-9=0 Please help and please show work if you can

Answer 1

Answer: x = 3, x= - 3

Step-by-step explanation:

x^2 - 9 = 0

=> x^2 = 9

=> x = 3, x= - 3

Answer 2

Answer:

x = 3 or -3

Step-by-step explanation:

So you have the equation x² - 9 = 0

Move the 9 to the other side: x² = 9

Then take the square root of both sides: $\sqrt{x^{2} }$ = ±$\sqrt{9}$

x = ±$\sqrt{9}$ = ±3

x = 3 or -3
