Recall the Laplace transform of a second-order derivative,
and the transform of cosine,
Here, both , so taking the transform of both sides of
gives
By graphing the polynomial, we conclude that there is only one real root, so the correct option is A.
<h3>How many roots has the given polynomial?</h3>
We have the polynomial:
To see how many real roots this polynomial has, we can graph it and see how many times the graph intercepts the x-axis.
The graph can be seen below:
There we can see that there is only one intercept, so there is only one real root.
So the correct option is A.
