ALGEBRA HELP!!!! 10 points

add 49 to both sides of the equation, then take the square root of both sides.x^2 = 49(Here, we add 49 to both sides to isolate the variable,add 49 to the right hand side,square root both sides,......
1.Solve the equation, if possible. Write irrational numbers in simplest radical form. Describe the strategy you used to get your solution and tell why you chose that strategy.

x^2 - 49= 0

-
x^2 - 49 = 0
+49 +49
x^2 = 49
√(x^2) = √(49)
x = 7

-
x^2 = 49
x = ±7

To get x by itself, add 49 to both sides of the equation, then take the square root of both sides. :)

Why did someone thumbs down my answer :(

-
x^2 - 49 = 0
x^2 = 49 (Here, we add 49 to both sides to isolate the variable, which is x)
x = 7 (Now we take the square root of both sides)

-
7
add 49 to the right hand side, which cancels out the 49 on the left
so now u have x^2=49
square root both sides, and you have x=7

-
x=+ or -7
