Answer:
B. 121
Step-by-step explanation:
Complete the square.
Take half of the middle term, 22, and square it.
So 11^2 = 121.
Answer:
54
Step-by-step explanation:
5-3=2
so you multiply 2 times 27.
2 times 27 is 54
Answer:
The correct answer is B- 21b+7bc
Step-by-step explanation:
7b(3+c)
(7b)(3+c)
(7b)(3)+(7b)(c)
21b+7bc
Given:
A fourth-degree polynomial function has zeros 4, -4, 4i , and -4i .
To find:
The fourth-degree polynomial function in factored form.
Solution:
The factor for of nth degree polynomial is:

Where,
are n zeros of the polynomial.
It is given that a fourth-degree polynomial function has zeros 4, -4, 4i , and -4i. So, the factor form of given polynomial is:


![[\because a^2-b^2=(a-b)(a+b)]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5E2-b%5E2%3D%28a-b%29%28a%2Bb%29%5D)
On further simplification, we get

![[\because i^2=-1]](https://tex.z-dn.net/?f=%5B%5Cbecause%20i%5E2%3D-1%5D)
Therefore, the required fourth degree polynomial is
.
