Answer:- The total number of roots in the given polynomial function is 2.
Explanation:-
We know that corollary of Fundamental Theorem of Algebra tells that polynomial will have exactly as many roots(m) as its degree(m>0).
The given polynomial function
is a quadratic polynomial with degree 2.
Thus by corollary of Fundamental theorem of algebra
The total number of roots in the given polynomial function must be 2.
