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

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

Explanation:

We have been given a quadratic equation
`x^2=(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:

`√(x^2)=\pm\sqrt{(9)/(16)}`

`x=\pm\sqrt{(9)/(16)}`

Therefore, option A is the correct choice.
