Question

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

Answer 1

the answer is C, I believe.

Answer 2

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

A is correct

Explanation:

We are given quadratic equation
`x^2=(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`

`√(a^2)=\pm√(25)`

`x^2=(9)/(16)` to solve for x

Taking square root both sides

`√(x^2)=\pm \sqrt{(9)/(25)}`

`x=\pm(3)/(5)`

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