Thanks for this video sir hindi ko po kasi nagets nung una but when I watched this vid nagets ko rin sa wakas.

Thankyou for this vid..this vid save me form failure

may mali po dun sa substitution sa number 3 sa finding the negative real zeros, walang 3 dun sa x³, x³ lng sya

I get it now po. Pero pano nmn po hanapin ang imaginary? BTW, THANKYOU FOR SO MUCH HELP SIR❤️

Good afternoon po sir!

na play na ng teacher namin yan sa online class

Salamat poooo😭😭❤️

Thank you po sir

Sir I would like to correct you if you don't mind when you look for the f(-x) you should not multiply the x by itself instead you should multiply it by its coefficient or the number beside it and just copy the exponent. Hehe

Thank youuu po sir

helpful :)

Next time sir, use your native language na lng or kahit magtataglish ka. Mahirap kasi itindihan ang lesson kung pinipilit gamitin ung hindi mong lengwahe. Kung nahirapan ka mag English, ibig sabihin nahirapan ka magexplain, at nahirapan din kmi maka itindi
