VARIABLE=Variable, In algebra, a symbol (usually a letter) standing in for an unknown numerical value in an equation. … Commonly used variables include x and y (real-number unknowns), z (complex-number unknowns), t (time), r (radius), and s (arc length).
CONSTANTTERM=
In mathematics, a constant 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. the 3 is a constant term.
Answer:
the constant term of the algebric expression is 225.
Given question -:
