Naah bro, jaise IxI ka graph +x,-x dono ke liye sketch hota hai na waise hi yeh graph bhi hoga, isliye 4 values aayengi. koi 5th value exsist nahi karegi...identity mein infinte values possible hain. www.transum.org/Maths/Activity/Graph/Desmos.asp Upar link par, 9x^2-18|x|+5=0 paste karke graph dekh le. 4 roots aa rahe.

I feel light while studying with NV Sir
for everyone who is getting answer of hw ques as -2:
(CORRECT ANS: 2)
1. sum of squares of numbers (or reciprocal) cant be negative.
2. in the ques , the coefficient of x is 0, so sign change would happen with the constant term i.e. 1(= -1)
now try it again, u will get the answer.
Hey but a+b+c=1 and ab+bc+ca=0 and abc=-1
So a^-2+b^-2+c^-2 = (a+b+c)²-2(ab+bc+ca)/(abc)² so shouldn't the answer be 1?
@@hriteshmaikap1054 you have taken LCM wrongly. It would come (bc)^2+ (ab)^2 + (ac)^2 / (abc)^2 so u can't use the identity which u have used in the answer

Your videos are quite informative. But, Condition 6 of Location of roots theory has been put wrong, this will give wrong answer as it also contains wrong graphs. Condition for both the interval limits should be taken separately.

Sir last question of location of roots me(0,1) interval ke karan f(0)f(1)

Equality is becoz of the condition that any of the 2 points could be on the parabola itself making f(x} equal to 0.
