Answer:
<u>212,400 items</u> were sold in 10 months.
Step-by-step explanation:
Given:
Items sold this month = 70,800
Percent Increase in every month = 20%
We need to find number of items sold in coming 10 months.
Solution:
First we will find number of items increase in each month.
number of items increase in each month can be calculated by Percent Increase in every month multiplied by Items sold this month and the divided by 100.
number of items increase in each month =
Now we will find number of item sold in 10 months.
number of item sold in 10 months is equal to sum of Items sold this month and number of items increase in each month multiplied by 10.
framing in equation form we get;
number of item sold in 10 months =
Hence <u>212,400 items</u> were sold in 10 months.
This is a polynomial of degree 2, and remember that complex roots always come in pairs; therefore, in a second degree polynomial you can only have 0 real roots and 2 complex roots, or 2 real roots and 0 complex roots. There is no way you can have 1 real root and 1 complex root because, as stated before, complex (non-real) roots always come in pairs; so the only way of having 1 real root is dumping the polynomial of degree 2 (
) by changing the 14 to 0. That way we'll left with 
which only has one real root:
