1. List the terms in the expression below, place a comma between each term.

19cd + 6d^2 + 8

2. List the coefficients in the expression below, place a comma between each coefficient.

-7y + 13ab^2 + x

• math -

Terms are separated by + or - signs.

1. The first term is 19cd.. Can you find the other two?

2. Coefficients are the numbers in front of the letters.

x can be written as 1x, so it has a coefficient of 1.

Can you find the others?

Terms are a combination of letters and numbers written next to each other.

They are separated by + or - signs.

3x + 4y + 9

represent 3 terms:

3x
4y
9

The coefficients are the numbers in front of the letters

3 and 4 are coefficients
9 is usually called a constant because it is just a number without a letter.

So, 1. 19cd , + 6d^2 , + 8 ,

2. -7
13

is it correct

• math -

2. -7 , y + 13 , ab^2 + x

-7
13

• math -

1. 19cd , + 6d^2 , + 8 ,

19cd

6d^2
