    You are using the formula (x+a)(x+b)(x+c). Here the coefficient of x square is the sum of a,b and c i.e a+b+c
    Next, the coefficient of x is (ab+bc+ca).

    If alfa= A beeta =B and gamma =C
    And the coefficient of x^3 is 1 then.....
    A×B×C= constant term
    A+B+C= coefficient of x^2
    AB+BC+CA= coefficient of x
    Old rule as in case of a quadratic equation.

    Question no. 3 m factor + - 1 or + - 5 hoga or isme s choose karke -7 banana hoga or iska product ka addition 11 ke equal lana hoga
    This is the process to solving these types of problems
    Thank you mam🙏💕

    ans- 6) +2 , -(1/2) , -3
    ans- 7) -2 , -3 , -4
    ans- 8) I think question is wrong , there should be -50 instead of + 50 and then the ans will be , -2 , -5 , +5
    N.B. Thank you for this awesome short trick , it helped me a lot ! 🙏

    There are two substitutions for cubics
    Niccolo Fontana proposed x=u+v substitution
    Francois Viete proposed y^2+xy=a to solve cubic equation
    in the form x^3+3ax=2b

  • @sadiq114
    @sadiq114 5 років тому +3

    Thank you very much for this short trick. But what about higher order ie x^5+---------+x=0 or x^6+-----------+x=0 etc.?

    • @amaralsady5869
      @amaralsady5869 3 роки тому

      expand (x+a)(x+b)(x+c)(x+d)(x+e)=0 then you will get the solution but it will be so hard because you will get a lot of letters.

  • @keshabkaflay9075
    @keshabkaflay9075 3 роки тому +2

    Thank you for the video. In question 4 one could also choose the factor- 1 x 2x8=16, instead of repeating 4 again. Or is there a special rule behind choosing 4 again to match -16x in the equation.! Could you explain.

    • @Shubham-ht4vm
      @Shubham-ht4vm 2 роки тому +1

      you can't get +1 for coefficient of x^2 in that combo of 1,2,8. that's why mam took her combination.

  • @satyamchandra6633
    @satyamchandra6633 5 років тому +27

    Hahahahhaa....this is easy whenever no sign change in the coefficient of the equation...
    But you can't get in otherwise case...
    So conclusion is here :- this is not applied for shortcut rule
    You can refer b.s.grewal's numerical analysis book if you want to explore this

    Hit and trial method is more convenient.
    Let us try: try X=1
    Both LHS =\ r h s
    Try with X= - 1
    This is one solution
    We can solve it
