    Bravo! Nice work. So when all is said and done there are no solutions in the real world because of the iota.

    Hi and thank you for your video.
    Another useful approach after minute 10:41 coud be:
    EQ1: (x+y)^3-3xy(x+y) = x^3 + y^3 = 10
    EQ2: (x+y)^2-2xy = x^2 + y^2 = 7
    -------------------------------
    Set EQ1 = EQ2 by xy
    [(x+y)^2 -7]/2 = xy = [(x+y)^3-10]/[3(x+y)]
    -------------------------------
    substitute (x+y) = u
    -------------------------------
    3u(u^2-7) = 2(u^3-10)
    -------------------------------
    u^3-21u+20
    find first solution and after that do division and solve qudratic equation
    u1=1; u2=4, u3=-5
    solve u: 6 solutions
    -------------------------------
    =>
    x^2+y^2 = 7
    from u=4:
    x+y = 4
    y = 4-x
    x^2 + (4-x)^2 = 7
    2x^2 - 8x +9 = 0
    x12 = [8±j*sqrt(8)]/4
    resubstitute

      Wow! Thanks for sharing this wonderful appreciate I will study it carefully and closely at my leisure time so that I can apply it in solving similar challenges of this kind in subsequent video tutorials sir.

      Just give it a detailed study for few times and you will discover it is easier than you thank sir/ma.

    It is usually required to solve equations in real numbers, unless the condition specifically states that complex roots are needed. It is not clear why p,q = 1, -3, which can give real roots, are rejected.

    Excellently explained. But we can minimize writing time by not repeating, thus shorten the video. Thanks for uploading. 2024.3.26

    If a is isolated in the left side
    And b and numbers in rigth side
    (8/4)^a=(..)/(..)
    2^a=(..)/(..)will be introduced in first equation.

    @danielkyei7173 10 месяцев назад

    Brother, you have done so well but there's a little mistake that needs to be corrected, even though it didn't affect the answer. It has to do with the factorization of the quadratic equation
    p²+p -20=0. The parentheses in the next step are wrongly placed.
    That's (p²+5p) - (4p -20) =0 is supposed to be written as
    (p²+5p) + ( -4p -20) =0
    Remember that if we expand these two equations we won't get the same result

    • @onlineMathsTV
      @onlineMathsTV  9 месяцев назад

      Thanks for appreciating our works here sir and thanks for the correction, it is well noted and I will be more careful in subsequent lectures sir.
      Maximum respect sir...👍👍💪💪💪

    I didn't understand why you rejected (p,q) with negative p or negative q...

  • @michelebrun613
    @michelebrun613 14 дней назад

    If you admit complex solutions you cannot reject (p1,q1) and (p3,q3)

    Horner's algorithm seems to me to be better than polynomial division. Less writing, and a faster way to the zeros of a polynomial.

    • @onlineMathsTV
      @onlineMathsTV  10 месяцев назад

      Ok, I will apply that in subsequent challenges sir/ma.

    19:07 - If you multiply 4*(p+5) it will be equal to 4p+20 not 4p-20.

    • @onlineMathsTV

      No sir, the minus at the back of 4 will change the plus sign to minus, so that expression is 100% correct. Thanks for watching and dropping this comment.
