Find the polynomial that the degree of 3 and has zeros: x = 3, -1, 2

• (x-3)(x+1)(x-2)

• (x+3)(x-1)(x+2)

• Don't count this one because I need to study more and retake it.

Find the polynomial that the degree of 4 and has zeros: x = 4i, 1, 2 

• (x+4i)(x-4i)(x-1)(x+2)

• (x-4i)²(x-1)(x+2)

• (x+4i)(x-4i)(x+1)(x-2)

• (x+4i)²(x+1)(x-2)

Select polynomial whose zeros and degree are given.
Zeros: – 5(multiplicity of 3), 9(multiplicity of 2), – 2, 4
Degree: 7

• (x + 5)³(x - 9)²
  (x + 2)(x - 4)

• (x + 5)³(x - 9)²
  (x + 2)⁷(x - 4)⁷

• (x + 5)³(x - 9)²(x + 2)

• (x + 5)(x - 9)(x + 2)
  (x - 4)
