Question

What is the first step in solving the quadratic equation x^2=9/16

Answer 1

The answer is C, I believe.

Answer 2

Answer:

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

A is correct

Step-by-step explanation:

We are given quadratic equation $x^2=\dfrac{9}{16}$

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:

$a^2=25$

$\sqrt{a^2}=\pm\sqrt{25}$

$x^2=\dfrac{9}{16}$  to solve for x

Taking square root both sides

$\sqrt{x^2}=\pm \sqrt{\dfrac{9}{25}}$

$x=\pm\dfrac{3}{5}$

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