Question

what is the first step in solving the quadratic equation x2 = 9/16 ? take the square root of both sides of the equation. add 9/16 to both sides of the equation. square both sides of the equation. subtract 9/16 from both sides of the equation.

Answer 1

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 2

Answer:

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

Step-by-step explanation:

We have been given a quadratic equation $x^2=\frac{9}{16}$. 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:

$\sqrt{x^2}=\pm\sqrt{\frac{9}{16}}$

$x=\pm\sqrt{\frac{9}{16}}$

Therefore, option A is the correct choice.
