People criticising the time constraint must understand, he has methodically broken down the whole problem and covered may topics step by step. While solving, I personally marked all values given in option on a number line and substituted the values which were repeated maximum no of times first and so on to eliminate options
Exactly, we don’t want a undefined value that’s the reason the range is greater and lesser than zero, those three values taken before weren’t the exact ones, the range values are, hope this helps
Baskar Sir, if I try to solve it by wavy line concept, don't you think that we will be spared of all the trouble of plugging in the values and will also save a considerable amount of time.
Hi, We have just calculated the zeroes of each component in the expression for the sake of plotting those zeroes into the number line to find the range of values satisfying x.
It might help to revisit our quant video lessons in a different order. As you go from videos establishing basics to higher-level practice questions, the pace might seem better. Can I suggest that you check out ua-cam.com/video/1oHjbTz6_zs/v-deo.html first? Good luck with your prep!

At 5:43, If the denominator is zero - the value of the expression will be undefined. Why are we considering this?
yeah exactly

The wavy line concept is way easier than the method used here. The way of plugging in values is not practical during the test.
Thank you. Excellent video. Will subscribe for the paid videos too.

Excellent explanation. much appreciated.
very useful video. thankyou for bringing this.
when we put values of x less than -0.33 or between -0.33 and 0, why inequality is not change?
the ineqality sign changes only when we multiply or divide by any negetive number. here we are just substituting the value. hope you find it useful.
@@rishibhardwaj7907 got it . thanx
sir , why is 0 a root here ?

Too fast
