In mathematics, a polynomial<span> is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. An example of a </span>polynomial<span> of a single indeterminate x is x</span>2<span> − 4x + 7.</span>
I guess you want to find the 4 numbers
x + x + 2 + x + 4 + x + 6 = -28
4x + 12 = - 28
4x = - 40
x = -10
so the numbers are -10, -8, -6 ,-4.
