Ответ:
f(x) has 3 real roots
Step-by-step explanation:
According to the Fundamental theorem of Algebra.
A polynomial of degree n has n roots, which can be real or complex or both.
Thus a polynomial of degree 3 has 3 roots.
Two real roots are given
Complex roots occur in conjugate pairs, thus there cannot be an odd number of complex roots.
Thus f(x) has three real roots.
