Learn how to simplify polynomials by combining like terms! Discover the power of adding and subtracting terms with the same degree of x. Uncover the magic of removing parentheses and …

If I have 6x's and I give you 8 more x's, you're going to 14x's. And then we have nothing here. And so if we just add nothing to negative 3, you're just going to get a negative 3. So this simplifies to, or when …

So let's get some practice simplifying polynomials, especially in the case where we have more than one variable over here. So I have 4x squared y minus 3x squared minus 2y.

Sal simplifies (x³ + 3x - 6) + (-2x² + x - 2) - (3x - 4).

Adding and subtracting polynomials is all about combining like terms. When the terms have two variables, it gets a little bit tricky to figure out which terms are like terms. In this article, we review …

Example: Add (2x²-3) and (7x³-4x+1).

We'll explore the connection between polynomials and the integers, through adding, subtracting, and multiplying polynomials. This prepares us for factoring and dividing polynomials, and paves the way …
