The constant in the polynomial equation 4x^2-12 is -12 and the variable is x
Step-by-step explanation:
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 x^{2}+2x+3, \ the 3 is a constant term.
Variable is a symbol (usually a letter) standing in for an unknown numerical value in an equation.
