Question: What is Polynomial ?

Answer:

2x3 + 5x2 – 8x + 1       y2 - 7y + 6       4z + 3 = 0
are examples of polynomials.

A polynomial function is a function whose terms each consist of constant multiplied by a power of a variable, such as 7y, 4z and 2x3

For example, x2 - 4x + 7 is a polynomial, but x2 - 4/x + 7x3/2 is not, because its second term involves division by a variable, and also because its third term contains an exponent that is not an integer.

Polynomials are one of the most important concepts in algebra and throughout mathematics and science. Polynomials are used to construct polynomial rings, one of the most powerful concepts in algebra and algebraic geometry.
