Algebra I Help: Dividing Polynomials with Missing Terms Part I

In this video, we practice dividing into a polynomial with missing terms.

You're fabulous and I love you. I feel like showing my teacher this and saying "This. This is how you do the teach." xD

This is the greatest video on the internet. Thank you so much.

You need to understand the standard form of a polynomial first. Once the polynomial is in standard form, it's obvious. So for example 3x^4 + 4x^2 + 7x -1 is missing the x ^3 term. Look at your exponents, they go in descending order. In my example, we started with the 4th power, missed the 3rd power, then saw a 2nd power, and 1st power.

Hello. “When terms are missing…”
How do I identify that a term is missing? Thank you for your help. (I realize this video is very old, but perhaps you’re still connected. 😊

What if the equation is negative should I also change the sign of the missing term to negative?

I always get confused on when to subtract and when to add when you have positive minus positive, negative minus negative or positive minus negative. I saw another video where it was a positive minus a negative and they added. On your video you have positive 20 -- (minus) -20 (negative) and you subtracted. The other video was 4x^2 -- -3x^2 and it was added to 7x^2. I'm confused??

How do you know if your missing a term though that’s where I’m stuck at help please!!

What if you have a missing term in your divisor?
