At the bottom we can expand by foil method so (2x+3)² becomes 4x+12x+9 and we also have -49 so we can add light terms of 9-49 to get -40. So our bottom is 4x²+12x-40 now we can take out 4 so we have 4(x²+3x-10) which if we use quadratic formula we can get x-2 and x+5 from the x²+3x-10 so our bottom is 4(x-2)(x+5) Now we have (x²-4)(x²+25) OVER 4(x-2)(x+5) at the top we can still expand (x²-4) because it's just (x²-2²) so it's (x-2)(x+2) Now our equation looks like this (x-2)(x+2)(x²+25) OVER 4(x-2)(x+5) It's basic math from here and there you go just cancel the x-2 and plug in the value>> <<@ashidashafeek2461 says : ഈ ക്ലാസ്സ്‌ നല്ല രസമുണ്ടായിരുന്നു💖. ഇനിയും നല്ല ക്ലാസ്സ്‌ പ്രതീക്ഷിക്കുന്നു🥹. ഈ ക്ലാസ്സിനു നന്ദി 😁🫀✨>> <<@marigonarexhaj6605 says : third>> <<@lemonthoughts31 says : but where does the -100 go ? 2:12>> <<@drewboden6981 says : Great video as always>> <<@wzkei17 says : you’re an absolute legend, thank you for getting me through a lot so far!!>> <<@goatmasterboi371 says : Bro its been like like 10 years and you're still doin this in the exact same style in the exact same tone of voice. I know for a fact you're hot as hell. Thank you for everything>> <<@tremacy7119 says : L'hopital rule can be used as when u substitute the limit in the given expression its 0/0 so we can just differentiate the expression and substitute the limit back in to solve it faster>> <<@TheCuteCyanBird2008 says : Very interesting! I love it! Just like Baldi difficult math!>> <<@thoughtfulworld1346 says : Im not here cause i have an exams or anything. almost done with uni and i wanted to dop by here and thank organic chemistry tutor for helping me since highschool till the almost end of my uni and to encourage yall an wish you guys luck>> <<@MaleWingDiver says : I just passed calc 2!! I'm done with the math portion of my bachelors in EET :D>> <<@heh5384 says : my life saver for spm and now its a month pass my last paper. pray that i get straight A+ !>> <<@vaishnavtamhane4016 says : 8th>> <<@ChidiebereDavid-y8p says : 6th from Nigeria ❤>> <<@1dantown says : L'hôpital's rule. 0/0. 16/(-21)>> <<@InkKulture222 says : Fifth from Nigeria>> <<@Love4every1_4 says : Forth from PHILIPPINES>> <<@NicolaSura-fz7os says : Third from ETHIOPIA>> <<@anesu9328 says : Second 😂>> <<@makailaandemilia7721 says : First>>
