Question

Look at the expressions.
-2×^3 -19×^2y -15×y. +11×^2y

What are the like terms?

Answer 1

`-19x^2y` and
`11x^2y` are like terms.

Explanation:

Recall what "like terms" means in an algebraic expression: Those terms that have the same variables at exactly the same exponents.

so in the expression:
`-2x^3-19x^2y-15xy+11x^2y` the second term and the fourth one are like terms. Notice that both terms have the variables:
`x^2y` with the variable "x" to the power 2, and with the variable y to the first power.

`-19x^2y` and
`11x^2y` are like terms.

Therefore, those are the only terms you can combine to reduce the expression.
