ELL Math NOTES Name _______________________ Topic: Combine Terms Period _______ Date_________ Questions/Main Ideas CLO: Combine terms to simplify expressions. Define nomial and give an example. Vocabulary: What Are “terms?” A term is an expression made up of numbers and/or letters connected by only multiplication and/or division. A term starts with either a + or a — sign. A + or — sign separates an expression into terms. What Are some Examples of Terms? a 3a is a term 3a2 — 4 3a2 is a term are two terms 3a2 — 4a is a term are two terms How many terms do you count here? 3a2 — 4a + 7 – 5y – 2 _______________________ What Are The Three Terms of 6b5 — 2a + 5 ? We‘ll separate the expression just before each + or — sign with a line. Prefix a + sign at the beginning of the expression. 6b5 The First Term is: 6b5 | — 2a | +5 The Second Term is: — 2a The Third Term is: + 5 How are Terms Different From Factors? Terms are combined, factors are multiplied. 7 terms. +x+y is an expression with three 7xy is a term with three factors. Both terms and factors can be rearranged. factors: 7+x+y=y+7+x 7xy = 7yx What Is A Nomial? A nomial is a name that we give to an expression with terms. many: muchos, muchas mas de dos puede ser “mucho” en algunos ejemplos matematicos. 3x + 4y - 5 + 6x - 7y is a _________________ A trinomial has three terms. For example, _____________________________ A binomial has 2 terms. For example, _____________________________ A monomial has only one term. For example, __________________________ might also be: The word polynomial is a general name used for expressions that have many terms. binomials and trinomials are also called _________________ Give an example of a NOMIAL: ________________ So a binomial might also be called a polynomial.
