Should add an annotation at 6:12 to say "No Real Solutions"

Great job.

thanks so much, never knew youtube taught me more than college :)

hey patrick, i have a question: why is the numerator of a rational expression considered irrelevant?

i have another question: for the third example, why couldn’t it be factored? the x was squared so why not factor the x squared plus 1?

algebra is tricky! study lots

very well explained

excellent job!

yea last one is not possible if you try it out

x2+1)(x2-1 – wrong

x2+1)(x2+1 – wrong

x2-1)(x2-1 – wrong

it wont solve out

what would you rather have to help you study, marijuana, or alcohol?

Thanks i understand it now.

gosh you saved my grade, thank you

i see a bunch of =0 faces

I UNDERSTAND!!!! my college PROFESSOR < Mr PatrickJMT . So easy to comprehend and easy to listen to. Very specific and explain all steps…A+++++++++++
