    Easy trick to solve first question is to know that the sum of first 'n' odd integers is n^2. So the given que directly represents (sum of first 57 odd integers)-(sum of first 13 odd integers) and que is finished....

    I usually solve like
    Agar ham sab brackets ki maximum power se multiply kare to 1275
    So hame ek degree kam karni hai .
    It could be done by selecting constant from (x+1) =1; or by selecting linear from (x-2)^2 which is 4 ; or quadratic term from (x+3)^3 which is equal to 9(3C1×x^2×3^1) ....
    Similarly 4C1×4 ....
    ...
    Aapke method me je problem aa rahi hai ke ham 3 vaar(x-3) ko kyu bahar rakh rahe hai ?

    • @gtimeducation
      @gtimeducation  6 ปีที่แล้ว +4

      To understand my method you can follow this logic also.
      Degree of polynomial is 1275. We are looking for coefficient of x^1274. So, sum of the zeros will be equal to (-co-efficient of x^1274/ coefficient x^1275). So, coefficient of x^1274 = -(sum of zeroes) = - (-1 + 2 + 2 - 3 - 3+ 4 + 4 + 4 + 4 .....) etc.

    • @gtimeducation
      @gtimeducation  6 ปีที่แล้ว +3

      I think you are asking in question where double sigma is there. It is simple, when i = j, we have i x j = i^2, and there is no need of sigma for j variable only i variable will do. If it is a doubt of triple sigma question then ask it again.

    Sir how to think in such a way that we can split the nth terms in T (r+1) -T (r)

    • @gtimeducation
      @gtimeducation  6 ปีที่แล้ว +6

      I sequence and series there is one section of series of this type in which we split the general term in T(r + 1) - T(r). It stars with elementary partial fraction. It requires practice of such questions then by some logical thinking you can split. If you are reading cengage books, you will find this topic at the end the theory just before subjective questions. One thing is clear in such questions we have to split the term otherwise there is no way to get this sum. Now keep thinking that splitting must benefit you like when u r splitting and write the terms by putting the values of r terms must be cancelled in some pattern. If it is not cancelling u rework.

    Like i ;j;k equal krne pe aapne 3 sigma ki jagah ek hi sigma likha
    Vo kaise
    at 32:0 k and j ko equal krne par jab subtract kr rahe hai to
    k ke saath vaala sigma gayab hi jo gya?
    Thoda please bta do i have confusion

    • @gtimeducation
      @gtimeducation  6 ปีที่แล้ว +1

      We want sum when i, j and k are distinct. So we first find sigma when i, j and k are independent which is equal to (sigma of 1 for i)(sigma of 1 for j) (sigma of 1 for k). In this sum there will be terms when i = j (k may be equal to this or not), j = k( i may be equal to this or not) and i = k (j may be equal to this or not). Now all these sums will be equal. when u make i = j or j = k or i = k, we get the same sum. So, i am subtracting sum when i = j three times (one for each i = j, j = k, i = k). Now doing this we have subtracted the case when i = j = k more than required times. So we are adding the sum when i = j = k two times to balance. If still doubt dont hesitate ask again.

      Sir i had clearity about this what u replied .
      But i wanted to know
      Jo expression subtract karte time likha vo kaise bana ; usme sirf 2 sigma hai
      I m clear about which cases to subtract or add .
      But i just wanted to know jab hamne k=j maan ke subtract kiya tab vaha pe only 2 sigma hai kya k=j karne c ham either k or either j only ek sigma hi rakhe. . ( Kaise)
      Je doubt hau
