To solve the equation \( 2x^2 = 20 \), we can start by simplifying it.
1. Divide both sides by 2:
\[
x^2 = 10
\]
2. Next, take the square root of both sides:
\[
x = \pm\sqrt{10}
\]
This indicates that there are two solutions: \( x = \sqrt{10} \) and \( x = -\sqrt{10} \).
So the number of solutions in the solution set is **two**.
The answer is **A. Two**.
