What is the constant term in the polynomial expression, and what does it represent?

Aconstant term is a term in an algebraic expression that has a value that is constant or cannot change, because it does not contain any modifiable variables. For example, in the quadratic polynomial

x
2
+
2
x
+
3
,

x^{2}+2x+3
the 3 is a constant term.

Set square i think so
