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:
The Answer is c4.(4)
Step-by-step explanation:
I thought the c4 joke would be funny.
Answer:
it's c
Step-by-step explanation:
divide it by 7 we get 3 /7
If the center is at (0, 0) and the vertex is at (20, 0), then the distance, a, is the length from the center to the vertex, 20. The distance from the center to the focus is c. The distance from the center to the focus is 16, so c = 16. The formula we use to find the focus is

. We have our c value and our a value, so we will sub in those to find b.

and 256 = 400 - b^2. -b^2 = -144, so b = 12. There you go!
Answer:
Jackie is incorrect. Since 2 pints equal 1 quart, she would need to multiply 12 by 2 to get the correct answer of 24 pints.
