Answer:
6x and -3x
Step-by-step explanation:
In the expression 6x + 8xy – 3x + 9y + 4x^2, let’s identify the like terms:
6x and -3x are like terms because they both have the variable x with the same power of 1.
8xy and 9y are not like terms because they have different variables (one has x and y, the other has only y).
4x^2 stands alone as a term with no other like terms.
Therefore, the like terms in the expression are 6x and -3x 12. The other terms are not like terms with each other.
