Since

x² = (9/16)

The first step is to take square root of both sides.

√x² = √(9/16)

x = 3/4

Answer:  take the square root of both sides of the equation

Answer:

A. Take the square root of both sides of the equation.

Step-by-step explanation:

We have been given a quadratic equation [tex]x^2=\frac{9}{16}[/tex]. We are asked to determine the 1st step to solve the given equation.

We can see that we have a x squared term of left side of equation. To solve our given equation, we need to take square root of both sides of equation as:

[tex]\sqrt{x^2}=\pm\sqrt{\frac{9}{16}}[/tex]

[tex]x=\pm\sqrt{\frac{9}{16}}[/tex]

Therefore, option A is the correct choice.
