What is the first step in solving the quadratic equation x^2=9/16
a. take the square root of both sides of the equation
b. add 9/16 to both sides of the equation
c. square both sides of the equation
d. subtract 9/16 from both sides of the equation

"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:

 to solve for x

Taking square root both sides

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

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6
