http://xlinux.nist.gov/dads/HTML/squareRoot.html WebApr 9, 2024 · The strategy for solving is to isolate the square root on the left side of the equation and then square both sides. First subtract 2 from both sides: √x − 3 = 4. Now that the square root is isolated, we can square both sides of the equation: (√x − 3)2 = 42. Since the square and the square root cancel we get: x − 3 = 16.

WebTo undo a square root, you raise it to the 2nd power (square it). What you do on one side you must do on the other side. So sqrt (n)^2 = n while sqrt (2n+6)^2 = 2n+6 This will leave you with n=2n+6 to solve for n.
