Hello Amandeep Sir..... I am Kathit from Gujarat.... How can u say that @14:16 that expression will always have a non negative value?? Please help me Sir....
Hi Kathit, Square of any expression is always non negative. If you look at (x+2)^2 and put any value of x you always get its square as positive and when you put x=-2 you get 0 Hence value is always non negative. Or in general remember (something)^even power = Non Negative
Sir.. suppose we've an equation (x-2)(x-3)(x-3)>0 Taking a no more than 3 eqn becomes +ve ie in graph +ve -ve +ve.. so our ans would be ( -infinity 2 ) U ( 3 +infinity) But if we put a no between 2 & 3 eqn again becomes +ve which contradicts the above ans
Hi Swapnel, I missed to reply on your comment, When we get same roots ( 3,3) then the curve bounce back or you can say will not change it's direction from + to - or from - to +.

Sir, have you covered all the topics and uploaded all the videos?
Hi Mayank, Almost
Some topics are yet to be done like Functions, Instalments Calculation, Trigonometry, Height & Distance, Mensuration 2D & 3D.
@@aptifyy Thank you sir,
I am waiting for that.
Also sir, Can you prepare some videos on CAT type questions?
Very Soon !
