Question

Solving Equations with Radicals. √x-2 =4

Answer 1

well square both sides of the equation,

then add 2

that should give you the value of x if the equation is

\[\sqrt{x -2} = 4\]

if the equation is

\[\sqrt{x} - 2 = 4\]

add 2 to both sides of the equation

then square both sides to find x

hope it helps

Answer 2

It;s the first one sorry I don;t know how to make that sign over all of them.
(√x-2)^2 = (4)^2
x-2+2=16+2
x=18
Would this be how I would do it?
