Answer:

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

A is correct

Step-by-step explanation:

We are given quadratic equation

We need to solve for x. We have to isolate x here.

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

sqare x2 +- sqre 9725

x=+- 3/5

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