Reverse FOIL (first, inner, outer, last) is another way of saying factorization by grouping. To factor a polynomial, find the product of the first and the last coefficients. Then, find the two factors of the product that add up to the middle coefficient. Split the middle term into two terms, and the
Algebra is a method of solving mathematical equations in a way that allows a person to derive unknown quantities, such as bank interest, percentages or proportions. The use of letter variables in algebra to represent unknown quantities coupled with the ability to rewrite equations makes it easier to
Algebra has its beginning in the cultures of ancient Egypt and Babylonia between 1800 and 1600 B.C. Mathematicians of the time could solve for unknowns, but only used positive numbers. Their mathematics involved the use of few symbols and is called rhetorical algebra.
In math, FOIL is an acronym that reminds people how to expand the multiplication of two expressions in parentheses. FOIL stands for First, Outside, Inside, and Last, which is the order in which one should multiply the terms in the parentheses.
Functions in Algebra 2 are classified into different categories that include quadratic functions, exponential and logarithmic functions, trigonometric functions and linear functions. Some common functions in algebra 2 are quadratic functions, which are represented by function terms such as f(x), whi
The main types of sets in algebra are the finite set, the infinite set, the singleton set, the null set, the subset and the proper set. A finite set is a set that has a predetermined number of elements as its members, while an infinite set does not have a predetermined number of elements, although i
From the ancient Babylonians to Islamic mathematicians to French philosophers, the history of algebra is the history of solving problems. With the rhetorical algebra of the Babylonians in BCE 2000, working with non-numeric objects using arithmetical operators to solve practical problems finds its ro
Elimination is a method for solving a system of two or more algebraic equations by transforming the system so that one of the variables cancels out. It is sometimes called the addition method because it involves adding equations together.
The standard form is one of two methods used to solve an algebraic linear equation. It exists in the form ax + by = c, where a and b are coefficients and x and y are parts of an ordered pair.
Algebra, in its earliest form, was first used by the Babylonians as early as 1700 B.C. It is possible that algebra was used before this time, but historical records are incomplete. However, the algebra used by early civilizations was much more rudimentary than the algebra currently in use today.
