Step-by-step explanation:
• Algebraic expression is formed from variables and constants using
different operations.
• Expressions are made up of terms.
• A term is the product of factors. Factors may be numerical as well as
algebraic (literal).
• Coefficient is the numerical factor in a term. Sometimes, any factor
in a term is called the coefficient of the remaining part of the term.
• The terms having the same algebraic factors are called like terms.
• The terms having different algebraic factors are called unlike terms.
• Expression with one term is called a 'Monomial’.
• Expression with two unlike terms is called a 'Binomial’.
• Expression with three unlike terms is called a 'Trinomial’.
• In general, an expression with one or more than one term (with nonnegative integral exponents of the variables) is called a ‘Polynomial’.
• The sum (or difference) of two like terms is a like term with coefficient
equal to the sum (or difference) of coefficients of the two like terms.
