Hw 1 mai ye 170 kha se aya kyuki bita ki value 18 h uska square krenge to 324 ayega and + alpha ka square 1 aayega to 325 hua aur upon mai alpha*bita vo 77 hogya ye thik h

In question 33:50, isn't the value of b will be -4k? You've taught us to take the negative sign as well right

[@wherearetheavacados6356]

|a| means we can ignore the -ve symbol as any number you put inside the | | will yield a positive result. So |-2|= 2 and |2| also equals 2. so while he did make a mistake not writing -4 ,ultimately because of mod | | the answer remains the same.

And if u wanna know how and why c/a =alpha*beta and why is alpha+beta = -b/a...... then its derived from eqn only explained in previous videos of mba wallah or just google it.... There is a post by brainly in google just see it how to derive that product of roots is c/a and sum of roots is -b/a gosh i cant write so many numerical signs and letters in youtube😂😂
