if x^2 = 49, then the square root property says you can take the square root of both sides as long as you make one a plus-minus.
x^2 = 49, which means
square root of x^2 = plus minus the square root of 49
the square root of 49 is 7, so +- 7. We get:
x = plus/minus 7 (this means either positive 7 or negative 7)

What square root property is essential to solve any radical equation involving square root?
If you take an equation such as Ax2+ Bx+c=0, you can complete the square and then use the square root property to solve it. That is how we derive the quadratic equation. For example, x2+2x-9=0 We write this as (x+1)2=10 bu completing the square then the square root property tell us that x+1 is PLUS OR MINUS Square root of 10
