Your welcome Brian! Glad my videos are helping you! Thanks for letting me know. Keep up the great work with your math!
Amazing! It was so easy, I thought it was so hard
for the second problem (2x+3) (x-2).for the inverted denominator
Mario the plug :))) You're the best man keep it up

How came that you cancel out the common term if its a monomial in binomial..?

Joey, I’m not sure I understand your question. You want to factor the numerators and denominators as much as possible first then see if you can cancel factors in the numerator and denominator. For example say the numerator was (x-3) and the denominator was (x+4) you would not be able to cancel just the x....that is a common mistake that students sometimes make...I’ll see if I can find any other videos I have that can help you....just a minute
why wouldn't you factor the (x^2+2x+4) further from the last example?

It’s because that is not factorable further.
Hi, I had a question and this term is getting me confused. So right not we are learning this but at the end of the answer we have x ≠ (a number) for our answer...but the thing is our teacher tells us that there is sometime you can put it and sometimes you dont need to

Set the denominators = to zero. Those are the excluded values …because you don’t want the denominator equal to zero because it would be undefined. Hope that helps you.

@@MariosMathTutoring thank you, i think that helps…but there is this other part where so my teacher said that sometimes you don’t have to include x not equal the number if it’s already visible in the final answer
