So precise and orderly. Really help this 74 year old to keep his brain percolating. Thanks!

Imagine everlasting life and what you personally doe ? This will give you an idea 💡 on how to get it + 16 All Scripture is inspired of God+ and beneficial for teaching,+ for reproving, for setting things straight,+ for disciplining in righteousness,+ 17

Great solution

Thanks, but it is too long. Once you got 'ab = 3' then you could substitute into the given 'a-b = 2' which would yield 'a^2 - 2a - 3 = 0', thus a = -1 and +3. Finally x+13 = (-1)^3 and (3)^3, that is, x = -14 and +14.

La explicación paso a paso, larga, pero aclara muchas dudas y hace razonar para bien. Gracias 👌👏👏

Bueno, me apasionan las matemáticas, y en ese idioma puedo hablar, también en castellano....y nada más, disculpas.

Carefully peruse this equation. There are two cube roots that differ by two. Its easy to find 14 as an answer. Sometimes inspiration is better than perspiration!!

короче решается зачем город городить, решается за 2 минуты имеем 'a-b = 2' находим b = a-2 и сразу подставляем в 'a^2 + 2ab +b^2 = 13 самом начале решаем квадратное уравнение и находим a = -1 и +3. затем возводим a^3 = x+13 и решаем находим x

You ought have applied quadratic solution from where you got ab=3 and a-b=3 to abridge the long route but great work

Yes, I was also thinking that.... He perhaps wants to make his video longer... 😅😅

İ think you chose the largest way 😂 A*2+ab+b2=13 A-b=2 (A-b)^2=a^2+b^2-2ab =4 3ab=9 a.b=3 So (a+b) ^2=16 a+b=4,-4

wait i don't get it. why do we have to do the expansion at 4:45?

x = 14 or x = - 14

Il est faux de dire que √16 = ±8, la racine d'un nombre étant toujours positif, il faut dire ±√16 = ±8, je remarque que tu fais souvent la même erreur 🙄🙄
