<u>Factored Form Of Polynomials </u>
If we know the roots of a polynomial as
the polynomial can be expressed in factored form as
We are given two of the three roots of the polynomial:
The other root must be the conjugate of the complex root:
Recall the product of two complex conjugate numbers is
The required polynomial is
This is the factored form of the polynomial where only real numbers appear
We need to find the value of a, such as
Thus the value of a is
The expression of the required polynomial is
