Answer:
x² - 10x + 34
Step-by-step explanation:
given the roots are x = 5 ± 3i then the factors are
(x - (5 + 3i))(x - (5 - 3i))
= (x - 5)² - 9i² ← expand (x - 5)²
= x² - 10 x + 25 + 9 → [ i² = - 1 ]
= x² - 10x + 34
the missing term is 10x
Answer:

Answer:
- 3 or 1 positive real zeros
- 0 negative real zeros
Step-by-step explanation:
The signs of the coefficients of the given terms are ...
+ - + -
There are three sign changes, so the number of positive real zeros is 3 or 1.
When odd-degree terms have their signs changed, the signs become ...
- - - -
There are no sign changes, hence no negative real zeros.
