Finally, I got to hear why we reduce it by even numbers! Other videos I checked skipped the explanation and left me in the dark. Thank you! I just wish youtube had your video listed higher on the search!
If there is no change in sign in either case of finding possible positive or negative roots, the only possible roots are complex roots. Ex. X^2+2=0. No sign change for positive roots. (-x)^2+2=0 i.e x^2+2=0 again no sign change for negative roots Then the two roots are complex roots only.
Best explanation on youtube for this topic
This is what I was searching for.

THANK YOU... SIR...!!!
What if there is 4 total roots and 3 or 1 positive and 1 and 0 negative roots? How do you make the table? Do you skip numbers?
Thank you so much Sir!!!
16:02 -(x^5)=(-x)^5
You know that you kept writing is instead of in?
where is part 2
🙂
what happens with the null roots? 😿😿
