Answer:
15+10=15
Step-by-step explanation:
Answer:
Step-by-step explanation:
✔️It’s a null set
Consider the given equation is 
and one of the 6 in the options is -6.
Given:
The equation is
To find:
The value of x.
Solution:
We have,
Subtracting 3 from both sides, we get
Divide both sides by -2.
Therefore, the value of x is -6.
You didn't give the fourth zero, but the answer is still false. If you have a root or an imaginary number as a zero, then its conjugate is also a zero. So if 8i is a zero, then -8i must also be a zero, and if 4i is a zero, then -4i must be a zero, with those zeros and -4, the number of zeroes exceeds the number of zeroes that a fourth degree polynomial can have.
