What is the smallest zero for the polynomial
Q. Is x to the power a polynomial?
no it is not a polynomial. here exponent of x is negative. but for polynomial exponent of variable must be positive integer.

Q. Can X be a polynomial?
For an expression to be a polynomial term, any variables in the expression must have whole-number powers (or else the “understood” power of 1, as in x1, which is normally written as x). A plain number can also be a polynomial term.
Q. Why is X not a polynomial?
A polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication and non-negative integer exponents of variables. √5 is a zero degree polynomial because it is just a constant. √x is not a polynomial because it has a non-integer exponent.
Q. How do you find all zeros of a polynomial function?
Find zeros of a polynomial function
- Use the Rational Zero Theorem to list all possible rational zeros of the function.
- Use synthetic division to evaluate a given possible zero by synthetically dividing the candidate into the polynomial.
- Repeat step two using the quotient found with synthetic division.
- Find the zeros of the quadratic function.

Q. What is a polynomial of degree 5?
Fifth degree polynomials are also known as quintic polynomials. Quintics have these characteristics: One to five roots. Zero to four extrema.
Q. How do you solve a polynomial of degree 5?
To solve a polynomial of degree 5, we have to factor the given polynomial as much as possible. After factoring the polynomial of degree 5, we find 5 factors and equating each factor to zero, we can find the all the values of x. Solution : Since the degree of the polynomial is 5, we have 5 zeroes.
Q. Why is there no formula for polynomials of degree 5?
And the simple reason why the fifth degree equation is unsolvable is that there is no analagous set of four functions in A, B, C, D, and E which is preserved under permutations of those five letters. This was fairly well understood by Lagrange fifty years before Galois theory made it “rigorous”.
