Step-by-step explanation:
No. A typical polynomial is a finite series of terms added together, where the first term is a constant, the second term is a constant(coefficient) multipled by a variable, such as x, the third term is a constant(coefficient) multiplied by this variable which is raised to the power of two, the fourth term is a constant (coefficient) multiplied by this variable which is raised to the power of three and so on. all powers are positive. Any of the constants can be zero. The polynomial becomes a power series if the number of terms is infinite. There are cases of polynomials that contain more than one variable.
