Identifying Factors and Coefficients in Expressions
Identify the factors and coefficients in each expression.
a. 7vw
SOLUTION
The factors are 7, v, and w. The coefficient is 7.
b. -5rst
SOLUTION
The factors are -5, r, s, and t. The coefficient is -5.
c. _y 3
SOLUTION
The factors are _1 and y. The coefficient is _1 . 33
d. cd
SOLUTION
The factors are c and d. The expression cd has an implied coefficient of 1.
Parts of an expression separated by + or - signs are called terms of an expression. A term that is in parentheses such as (y +_2) can include a plus or minus sign.
Hint
_y = _1 y 33
cd = 1cd
4x
x - 4xym
two terms
(y + 2) -8 one term
p
5+1
3x + 2y -10 three terms
You can refer to a particular term of an expression by its placement within the expression. The terms of an express_ion are numbered from left to right, beginning with the first term.
x + 4xym - 6p - 8 (y + 2)
1st term 2nd term 3rd term 4th term
