  5. Quiz Review 1. Determine the maximum number of zeros for each function. 3 5

  6. Finding the zeros of a function • Find all zeros • Find the real zeros • Given that one zero is 5+2i, find the remaining zeros for

  7. Writing functions • Write the 3rd degree polynomial function with zeros 5, -5+2i. • Write as a product of linear factors And find the zeros.

  8. Complex numbers What real numbers a and b make the equation true. • (a-6) + (b-7) i = 11 + 3i • (a+3) + (b+8)I = -12 + 17i a=17, b=10 a=-15, b=9
