Hello Mr Whitt, I dont understand how you factored those denominators on example 7, I have watched all your factoring videos but dont remember you showing this kind of problem. Do you perhaps have a video showing how to factor these kind of problems

@FortBendTutoring 8 жыл бұрын

It's the same process that's in this video, kzfaq.info/get/bejne/p5yPo7qay76vk4U.html, just add the other variable with each 2nd term in the parentheses. You can then multiply your factorization to confirm it's correct.

Hello to you, good sir. In the #3, I was a little bit confused. When you factor by the numerator, don't you do the same with the denominator? Thank you.

Not in this case because the denominator can't be factored and it already matches one of the factors of the numerator in its current form.
