Step-by-Step Solution
Definition of Polynomial\nA polynomial is an expression consisting of variables and coefficients combined using only addition, subtraction, and multiplication. It is a finite sum of terms, each term being a product of a variable raised to a non-negative integer power and a coefficient.
General Form of Polynomial\nThe general form of a polynomial in one variable is:\nax^n + bx^(n-1) + cx^(n-2) + ... + k
\nwhere a, b, c, ..., k are constants and n is a non-negative integer.
Degree of a Polynomial\nThe degree of a polynomial is the highest power of the variable in the polynomial. For example, in the polynomial 3x^2 + 2x - 4, the degree is 2.
Examples
- 2x^2 + 3x - 1 (degree 2)
- x^3 - 2x^2 + x + 1 (degree 3)
- 5 (degree 0)
Conclusion\nIn conclusion, a polynomial is a mathematical expression consisting of variables and coefficients combined using only addition, subtraction, and multiplication. The degree of a polynomial is the highest power of the variable in the polynomial.
