Answer:
The additional roots of a polynomial equation is 10 and -14
Step-by-step Explanation:
Given that the polynomial equation with rational coeffients has the roots
7+3,2-16
To find the two additional roots:
The polynomial equation with coeffients in rational, complex
roots and irrational roots may occur in conjugate pairs.
The roots are 7+3,2-16
7+3=10 and 2-16=-14 (adding the terms)
Therefore the additional roots of a polynomial equation is 10 and -14
Answer:
0+7i
Step-by-step explanation:
The real part of the expression ('a') is zero. We have shown that, so it will be in the required form. Ordinarily, 0 would not be shown when writing this number.

We have taken the question to mean the principal square root. -7i is also a root of -49.
Based on the statement below, if d is the midpoint of the segment AC, the length of the segment AB is 4.5cm.
<h3>What is the line segment about?</h3>
in the question given,
AC = 3cm,
Therefore, AD and DC will be = 1.5cm segments each.
We are given C as the midpoint of segment DB.
So CB = 1.5cm.
The representation of the line segment is:
A-----------D------------C-------------B
1.5 1.5 1.5
Since AD, DC and CB are each 1.5cm segments. Then the equation will be:
= 1.5 + 1.5 + 1.5
= 4.5
Therefore, The length of the segment AB is 4.5cm.
See full question below
If D is the midpoint of the segment AC and C is the midpoint of segment DB , what is the length of the segment AB , if AC = 3 cm.

Answer:
you would start out with 90 because 90-12 = 78
so the equation could be
A= 90
