Step-by-step explanation:
If -4 + 5i is a root of a polynomial, then it's conjugate -4 - 5i will also be a root of the same polynomial.
Therefore, the polynomial has 4 degree, and zeroes are (- 4 + 5i), (- 4 - 5i) and -1 with multiplicity 2.
Hence, the polynomial will be

⇒ ![f(x) = [x^{2} + 8x + (4 - 5i)(4 + 5i)] (x + 1)^{2}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Bx%5E%7B2%7D%20%2B%208x%20%2B%20%284%20-%205i%29%284%20%2B%205i%29%5D%20%28x%20%2B%201%29%5E%7B2%7D)

Answer:

Step-by-step explanation:

Answer:
-2/3
Step-by-step explanation:
-2 (6a +1) + 5 <11
1) -12a-2+5 <11
2) -12a+3 <11 add -2 and 5
3) -12a < 8. subtract 3 from each side
4) a >8/-12. divide by -12 and flip the
enequality
5) a> -2/3. simplify your fraction
The answer for the first quartile would be 51.5
