"In this video I'm just going to multiply a ton of polynomials, and hopefully that will give you enough exposure to feel confident when you have to multiply any for yourself!" Nice way to start a video with some energy!

many years, back in the school I left my class of math because I was so terrified of it. I did not do well in school and the worst is that I left the school completely , not body in my life care at that time,why I left the school,but I wish that At that time there was youtube where you can learn real math...Thanks again to the teacher

To those who think this form of math is useless, your wrong. Most elementary and middle school math courses were meant to be used in everyday life. Now, in advanced math, this is all about testing your comprehension; what you can handle without imploding yourself. It's hard, and that's the point. It gets you used to being able to maintain several objectives at the same time, a skill that is used in adulthood. Not everything is direct you math haters...

So when Multiplying a trinomial why is that when you do that cross multiplacation step why do you just cut the numbers in half to cross multiply. How would you do this witha equation with a odd number

2x(4x-5)= 8x2 -10x so after that do i solve 8x2-10x= -2x or is my final answer just 8x2-10x???
If you were my math teacher, math would be my highest subject
This was a great video but how would you solve something like this: 2 (x-1)(x+3)?
@danielbonsu1139
5 жыл бұрын
You can multiply it anyway you want, but the recommended method is to multiply the binomials first, then multiply the result by the monomial. so (x-1)(x+3) = x^2+2x-3. then multiply the whole thing by 2, so 2*(x^2+2x-3) = 2x^2+4x-6
