There are infinitely many polynomials which meet the requirement.The polynomial is x2 + (-a - bi - 3)x + (2a - 2bi - ai + b) = 0and the other root is x = a + bi.There is nothing in the question which requires its coefficients to be real.
A fifth degree polynomial.
The actual equation itself is the polynomial. There is no polynomial for it, and your question doesn't really make sense.
It is a quadratic polynomial.
7X^3 Third degree polynomial.
what kind of polynomial is shown 3x3+x+1
Both - a polynomial expression, if you like.
The degree of this polynomial is 2.
As a polynomial in standard form, x plus 5x plus 2 is 6x + 2.
