How do you identify the terms, like terms, coefficients and constants in each expression: 8 + 6t - 3t + t?

Answer 1

Terms in a maths expression are similar to words in an English sentence. They are separated from one another by + and signs.

#8 +6t-3t +t# has 4 terms before it is simplified.

Like terms are those which have exactly the same variables

#6t-3t +t# are all like terms, because they are have #t#

A variable represents a number and can change its value. A constant always has the same value - these are the numbers which we use in maths. A number is a constant.

In this expression , #8# is the constant.

The coefficient of a term is the part that stands with another part. The number in front is usually called the numerical coefficient, while the variable part is called the literal coefficient.

In #5x^2#, the numerical coefficient is 5. The literal coefficient is #x^2#
#5x^2 = 5 xx x xx x#
The coefficient of #x# is #5x#
In #3xy^2#, 3 is the coefficient, #xy^2# is the literal coefficient.
#3xy^2 = 3xx x xx y xx y#

When asking for a coefficient, it should be specified which coefficient is required.

The coefficient of x is #3y^2#
The coefficient of y is #3xy# The coefficient of xy is #3y# The coefficient of 3x is #y^2# The coefficient of 3y is #3xy#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
