Polynomial division introduction | Algebra 2 | Khan Academy

Keep going! Check out the next lesson and practice what you’re learning:

When we divide the polynomial p(x) by q(x) we are basically asking "what should we multiply by q(x) to get p(x)?" If this sounds familiar, it's because it's very similar to dividing numbers! In this introduction we see how some quotients end up as a polynomial, while other times we have a remainder and cannot express the quotient as a polynomial. This is very similar to quotients of integers!

I was just watching your "red blood cells" video, does the Pulmonary Capillaries collect oxygen from the Alveoli? and heres another question, so the blood in the heart goes from the Pulmonary Artery and then into the left Lung, how does the right lung get blood, is it lung to lung? or is it something to do with the right side of the heart
