Answer:
"Take the square root of both sides of the equation"
A is correct
Step-by-step explanation:
We are given quadratic equation [tex]x^2=\dfrac{9}{16}[/tex]
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:
[tex]a^2=25[/tex]
[tex]\sqrt{a^2}=\pm\sqrt{25}[/tex]
[tex]x^2=\dfrac{9}{16}[/tex] to solve for x
Taking square root both sides
[tex]\sqrt{x^2}=\pm \sqrt{\dfrac{9}{25}}[/tex]
[tex]x=\pm\dfrac{3}{5}[/tex]
Hence, "Take the square root of both sides of the equation"
