Given:
2√(x + 2) - 3 = 7
Add three to both sides:
2√(x + 2) = 10
Divide both sides by two:
√(x + 2) = 5
Square both sides:
x + 2 = 25
Subtract two from both sides:
x = 23
Yes and x = 2+square root of 6 or x = 2-square root of 6
What square root property is essential to solve any radical equation involving square root?

If x squared -10 = 0 then x = the square root of 10

whp do you do a 7 suared
First, get the radical by itself. Then, square both sides of the equation. Then just solve the rest.
Square both sides of the equation to get rid of the radical sign. Then just solve as you normally would. Good luck! :-)
