Hi, Note highlighted for previous typo
Find a polynomial, step by step, having real coefficients, 
with the degree and zeroes indicated: 
degree 3, x = -5, x = -3i. The lead coefficient is 1.
Note:if a quadratic polynomial has complex roots, 
they will always be a complex conjugate pair! 
that is: root x = -3i will be accompanied by root x = 3i
 (x+3i)(x-3i) = x^2 + 9   |i^2 = -1
AND...
({{{highlight( x +5)}}})(x^2 + 9) = x^3 + 5x^2 + 9x + 45
