Question 104867
Identify the terms, like-terms, coefficients, and constant terms of:
-4k-12+3k
The terms are the monomials separated by a + or a -, so they are:
-4k, -12, 3k Notice that we usually include the sign preceeding the term.
The like-terms are the terms (more than one of them) that have a common variable, in this case it's k, or if there are terms (more than one of them) that have no variable, then those together would be like- terms.
-4k, and 3k
The coefficients are the numbers just in front of the variables.
-4 and 3
Constant terms are those terms that have no variables attached.
-12 is the only constant term, again, notice the negative sign is included.
Simplify: (By the way, it is not an equation but an expression)
-4k-12+3k Combine the like-terms together.
(-4k+3k)-12 this becomes -k-12 when you combine -4k and +3k
