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