Required
Determine the other zero
The zeros can be represented as:
Considering the 3rd zero, which is a complex number.
If a polynomial has a complex number as one of its zeros, then its conjugate pair is the corresponding zero
A conjugate pair is given as:
and
For
The conjugate pair is:

Answer:
The number of candles each girl needs to sell so that the total amount raised is the same for both is
<em>Hailey </em>70 candles
<em>Kacie </em>40 candles
Step-by-step explanation:
Let
x------> the number of candles sold
y----> total amount raised
we know that
<em>Hailey's equation</em>
-----> equation A
Please note that Hailey has already raised $160, so he has sold 40 candles.
<em>Kacie's equation</em>
-----> equation B
Please note that Kacie has already raised $70, so he has sold 10 candles.
equate equation A and equation B solve for x
The number of candles each girl needs to sell so that the total amount raised is the same for both is
<em>Hailey</em>
40+30=70 candles
<em>Kacie</em>
10+30=40 candles
