Answer:

"Take the square root of both sides of the equation"

Here square on x. So, first we get rid of square.

Taking square root both sides to get rid of square.

For example:

a2=25

sqare a2  = +- sqare 25

x2=9/16 to solve for x

x=+- 3/5

Hence, "Take the square root of both sides of the equation"
