Types of Polynomials Based on their Degrees In general g(x) = ax 4 + bx 2 + cx 2 + dx + e, a ≠ 0 is a bi-quadratic polynomial.īased on the degree of the polynomial the polynomial are names and expressed as follows:
In general g(x) = ax 3 + bx 2 + cx + d, a ≠ 0 is a quadratic polynomial.Ī polynomial having its highest degree 4 is known as a Bi-quadratic polynomial.įor example, f (x) = 10x 4 + 5x 3 + 2x 2 - 3x + 15, g(y) = 3y 4 + 7y + 9 are quadratic polynomials. In general g(x) = ax 2 + bx + c, a ≠ 0 is a quadratic polynomial.Ī polynomial having its highest degree 3 is known as a Cubic polynomial.įor example, f (x) = 8x 3 + 2x 2 - 3x + 15, g(y) = y 3 - 4y + 11 are cubic polynomials. In general g(x) = ax + b, a ≠ 0 is a linear polynomial.Ī polynomial having its highest degree 2 is known as a quadratic polynomial.įor example, f (x) = 2x 2 - 3x + 15, g(y) = 3/2 y 2 - 4y + 11 are quadratic polynomials. In general f(x) = c is a constant polynomial.The constant polynomial 0 or f(x) = 0 is called the zero polynomial.Ī polynomial having its highest degree Aries is called a linear polynomial.įor example, f(x) = x- 12, g(x) = 12 x, h(x) = -7x + 8 are linear polynomials. It has no variables, only constants.įor example: f(x) = 6, g(x) = -22, h(y) = 5/2 etc are constant polynomials.
are equal to zero polynomial.Ī polynomial having its highest degree zero is called a constant polynomial. The degree of zero polynomial is undefined because f(x) = 0, g(x) = 0x, h(x) = 0x 2 etc. Any non - zero number (constant) is said to be zero degree polynomial if f(x) = a as f(x) = ax 0 where a ≠ 0. If all the coefficients of a polynomial are zero we get a zero degree polynomial. īased on the degree of a polynomial, we have the following names for the degree of the polynomial. the highest power of the variable in the polynomial is said to be the degree of the polynomial.į(x) = 7x 2 - 3x + 12 is a polynomial of degree 2. To find the degree all that you have to do is find the largest exponent in the given polynomial.į(x) = x 3 + 2x 2 + 4x + 3. The highest degree exponent term in a polynomial is known as its degree. In this article let us study various degrees of polynomials.
The degree of a polynomial is nothing but the highest degree of its exponent( variable) with a non-zero coefficient. To recall an algebraic expression f(x) of the form f(x) = a 0 + a 1 x + a 2 x 2 + a 3 x 3 + ……………+ a n x n, there a 1, a 2, a 3 ….a n are real numbers and all the index of ‘x’ are non-negative integers is called a polynomial in x.Polynomial comes from “poly” meaning "many" and “nominal” meaning "term" combinedly it means "many terms"A polynomial can have constants, variables, and exponents. We have studied algebraic expressions and polynomials. In mathematics, a binary quadratic form is a quadratic homogeneous polynomial in two variables ( July 2009) ( Learn how and when to remove this template message) Please help to improve this article by introducing more precise citations.
