9n 8x, 8 is a constant
Answers
Answer:Terms, Like Terms, Coefficients, and Constants:
When we look at the expression, 4x +3− 2x − 7,
we must learn to identify certain vocabulary
words that pertain to it.
The terms are the number of parts in the
expression. In this particular expression, (4x),
(3), (–2x), and (–7) are all terms. Because of
this, there are four terms in the expression.
Consider the following expression:
8x
2 + 5x − 2 + 6 − 4x
How many terms are in it?
The like terms are the terms that can be put
together. (9x) and (3x) are like terms because
they both have an x attached. (–5) and (3) are
like terms because they have nothing attached.
Consider the following expression:
3x
2 + 7x − 2 − 4x
What are the like terms?
The coefficients are the numbers that are
attached to variables. In the term (5x), the
number (5) is a coefficient because it is
attached to x. In the term (–3x2
y), the number
(–3) is a coefficient because it is attached to
x2
y.
Consider the following expression:
4x
2 + 5x −3− 2x
2
What are the coefficients in the expression?
The constants are the numbers that are NOT
attached to anything. In the expression, 3x + 2,
(2) is a constant because it is not attached to
anything. The (3) is not a constant because it
is attached to x, and it is actually a coefficient.
Consider the following expression:
8x
2 −3+ 5x + 6 −8y
What are the constants in the expression?
Simplest Form and Combining Terms
An expression is in simplest form when no like
terms are found in it. Consider the two
expressions:
8x
2 − 5x + 6 9x
2 + 2 −3x −8
The first IS in simplest form, but the second is
NOT in simplest form. Be sure to work on
telling the difference.
