Polynomials are sums of terms of the form k⋅xⁿ, where k is any number and n is a positive integer. For example, 3x+2x-5 is a polynomial.  Kalakrit (Dubbing) video https://cdn.kastatic.org/googleusercontent/ZCdwTudJg6e6n-P2gsaUborP4izvMsGo71pvEVlX9dNYWcLXcP7VHkWpn2grt4TUP1KoJLQP9NswyHBuBLSFTBw Polynomials intro This introduction to polynomials covers common terminology like terms, degree, standard form, monomial, binomial and trinomial.

In this video, we explore two special cases: the constant polynomial and the zero polynomial. Why is the degree of a constant polynomial zero? And why is the degree of a zero polynomial undefined? We'll clear it all up with simple examples and visual explanations to make these abstract ideas easy to grasp! Courses on Khan Academy are always 100% free.

We discovered that when we combine or take away the same variable, we can simply count them up or down. For example, 5x minus 2x equals 3x. This helps us understand basic algebra concepts.
