Binomial. A binomial is an algebraic expression that has two non-zero terms. Examples of a binomial expression: a2 + 2b is a binomial in two variables a and b. 5x3 – 9y2 is a binomial in two variables x and y.

A Binomial number is an integer obtained by evaluating a homogeneous polynomial containing two terms, also called a binomial. The form of this binomial is , with and . However, since is always divisible by , when studying the numbers generated from the version with the negative sign, they are usually divided by first.

A binomial coefficient equals the number of combinations of r items that can be selected from a set of n items. It also represents an entry in Pascal's triangle. These numbers are called binomial coefficients because they are coefficients in the binomial theorem.

A rational algebraic expression (or rational expression) is an algebraic expression that can be written as a quotient of polynomials, such as x2 + 4x + 4. An irrational algebraic expression is one that is not rational, such as √x + 4.

How can we solve it? An algebraic expression is a combination of integer constants, variables, exponents and algebraic operations such as addition, subtraction, multiplication and division. 5x, x + y, x-3 and more are examples of algebraic expression.

A trinomial is an algebraic expression that has three non-zero terms. Examples of a trinomial expression: x + y + z is a trinomial in three variables x, y and z. 2a2 + 5a + 7 is a trinomial in one variables a.

Another useful way of thinking about polynomial and rational expressions is that polynomial expressions are those algebraic expressions that can be evaluated using a finite number of additions and multiplications (and subtractions), whereas rational expressions may also require division for their evaluation.

A quadratic expression (Latin quadratus ≡ ”squared”) is an expression involving a squared term, e.g., x2 + 1, or a product term, e.g., 3xy − 2x + 1. (A linear expression such as x +1 is obviously non-quadratic.)

MonomialA monomial is an expression made up of only one term. PolynomialA polynomial is an expression with at least one algebraic term, but which does not indicate division by a variable or contain variables with fractional exponents. TrinomialA trinomial is a mathematical expression with three terms.

You call an expression with a single term a monomial, an expression with two terms is a binomial, and an expression with three terms is a trinomial. An expression with more than three terms is named simply by its number of terms. For example a polynomial with five terms is called a five-term polynomial.

A polynomial equation with two terms usually joined by a plus or minus sign is called a binomial. ... A classic example is the following: 3x + 4 is a binomial and is also a polynomial, 2a(a+b) 2 is also a binomial (a and b are the binomial factors).

For example, 2(3 + 8) is a numeric expression. Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.

In algebra, a binomial is a polynomial that is the sum of two terms, each of which is a monomial. It is the simplest kind of polynomial after the monomials.

To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.

Expression with two unlike terms is called a 'Binomial'. Expression with three unlike terms is called a 'Trinomial'.

Numeric expressions apply operations to numbers. For example, 2(3 + 8) is a numeric expression. Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.

Binomial factors are polynomial factors that have exactly two terms. Binomial factors are interesting because binomials are easy to solve, and the roots of the binomial factors are the same as the roots of the polynomial. Factoring a polynomial is the first step to finding its roots.
