Which of the following is the complete list of roots for the polynomial function

a–3 + 2i, –3 – 2i
b–2, –4
c–2, –4, –3 + 2i, –3 – 2i
d–2, –4, –3 + 2i, 3 + 2i

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
