How do you identify the terms, like terms, coefficients and constants in each expression a+1+2a+8a?

Answer 1

See explanation

The terms of an expression are the things separated by the plus and minus signs. In this case, they would be #a,1,2a,#and #8a#.

The coefficients of an expression are the numbers that precede the variable in the expression. In this case they would be #1# (since #a=1a#), #2# and #8#.

The constants of an expression are the numbers which do not have a variable next to them. In this case, they would be #1#.

To identify the terms, like terms, coefficients, and constants in the expression (a + 1 + 2a + 8a):

Terms: (a), (1), (2a), (8a)
Like terms: (a) and (2a) are like terms because they both have the same variable, (a).
Coefficients: The coefficients are the numerical factors that multiply the variables. In this expression, the coefficients are (1), (2), and (8).
Constants: Constants are terms without variables. In this expression, (1) is the constant term.

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.
