Number of zeros theorem:
If multiple zeros are counted individually, the polynomial function P(x) with degree \(n(n > 0)\)
has exactly n zeros among the complex numbers.
The Polynomial Factorization Theorem:
If \(n > 0\) and P(x) is an nth-degree polynomial function, then P(x) has exactly n linear factors:
\(P(x) = a_{n}(x - c_{1})(X - c_{2})(X - c_{3}).....(x-C_{n})\)
Where \(c_{1},c_{2},c_{3},....,c_{n}\) are numbers and \(a_{n}\), is the leading coefficient of P(x).
Finding zeros:
Given:
\(P(x)=x^{40}+x^{39}\)
According to the Number of zeros theorem, the polynomial function P(x) has n zeros.
Where n is the degree of the polynomial function
Here \(n = 40\)
Hence the zeros of the polynomial function \(P(x) = x^{40} + x^{39}\) is 40
Finding linear factors:

Final statement:
The number of linear factors of the polynomial function \(P(x) = x^{40} + x^{39}\) are 40.
The zeros of the polynomial function \(P(x) = x^{40} + x^{39}\) are 40.
