Answer 2

Answer

Like terms: When the terms have the same algebraic factors. (Ex: 2x, 3x, 4x)

Unlike terms: When the terms have different algebraic factors (Ex: 2x, 3x2, 4y)

Monomial: An algebraic expression having only one term. (Ex: 2x)

Binomial: An algebraic expression having only two terms. (Ex: 2x+1)

Trinomial: An algebraic expression having only three terms. (Ex: x2+x+1)

Polynomials: An algebraic expression having one or more than one terms.

Note: Amonomial, a binomial and a trinomial are all polynomials.
