The value of m + n from getting the values of m and n from the constant polynomial P(x) = (2m - 4)x² + (5 - n)x + 13 is; 7
<h3>What is a constant polynomial?</h3>
A constant Polynomial is defined as a polynomial is a function of the form f(x) = a
where a is a real number, whose highest degree is zero.
Thus, examples of constant Polynomials are f(x) = 5, g(x) = -11 , h(y) = 7/4
Now, we are given the polynomial expression;
P(x) = (2m - 4)x² + (5 - n)x + 13
From the definition of constant Polynomials, we can say that;
2m - 4 = 0 and 5 - n = 0
Thus;
m = 2 and n = 5
Then, m + n = 2 + 5 = 7
