SECTION A

help me understand this type of a question by answering it.

give me accurate and correct answers.

1. Given that the complex number z = -2 + 7i is a root to the equation:

a) z³+ 6 z²+ 61 z + 106 = 0

b) find the real root to the equation.

2.P(z) = z⁴+ a z³+ b z²+ c z + d is a polynomial where a, b, c and d are real numbers.

Find a, b, c and d if two zeros of polynomial P are the following complex numbers: 2 - i and 1 - i

Question:

CASE STUDY; The body also uses ions to control fluid levels and blood pressure. The most-used ions in the human body are sodium, potassium, calcium, magnesium and chloride. Ions are also created whenever you electrostatically charge an object, such as when you rub a balloon on your hair. For this reason, your clothes dryer machine can be thought of as an ion maker. As clothes rub together in the machine, electrons get knocked from one atom to another. The result is the all-too familiar static cling. Electricity and strong electric fields perform a good job of creating ions (think lightning).
