Complex zeros exist in conjugate pairs so the fourth zero is 5 - 4i
So we have
P(x) = ( x - 3)(x + 13)(x - (5 + 4i))(x - (5 - 4i))
= (x - 3)(x + 13)( x - 5 - 4i)(x - 5 + 4i)
= (x^2 + 10x - 39)(x^2 - 5x + 4ix - 5x + 25 -20i - 4ix + 20i -16i^2)
= (x^2 + 10x - 39)(x^2 - 10x + 41)
= x^4 - 10x^3 + 41x^2 + 10x^3 - 100x^2 + 410x - 39x^2 + 390x - 1599
= x^4 - 98x^2 + 800x - 1599 Answer
Answer:
D. Angle P, Angle OPQ, Angle QPO
Step-by-step explanation:
The angle is at P so P must be either between the two other letters or be by itself so D is the correct answer.
