The equation of the polynomial in factored form is (x+2)(x+6)(x-10) = 0
<h3>What is a polynomial?</h3>A polynomial is an algebraic equation with at least the power of its variable 3.
Analysis:
if -2, -6, -10i are the zeroes of the polynomial, it means x = -2, x = -6, x = -10i
if x = -2, (x+2) is a factor, (x+6) is a factor.
convert x = -10i to a real number,
i =
-10 = 10
= 10
= 10
x = 10, so (x-10) is a factor.
Therefore equation of the polynomial in factored form is (x+2)(x+6)(x-10) = 0

Answer:
The number of CDs sold last week was 84 and the number of CDs sold this week was 26
Step-by-step explanation:
Let
x ---> number of CDs sold last week
y ---> number of CDs sold this week
we know that
Last week she sold 6 more than 3 times the number of CDs that she sold this week
----> equation A
Ms. Lott’s sold a total of 110 CDs over the 2 weeks
----> equation B
Solve the system by substitution
substitute equation A in equation B
solve for y
Find the value of x
therefore
The number of CDs sold last week was 84 and the number of CDs sold this week was 26
