How insane am I for looking at a title for a math video, going to my notebook and solving the problem, then checking the video for the "intended" sol^n?
Follow my move guys❤🎉🎉 First x=1,then 1³+1-10=0 1+1-10=0 2-10=0 Not equal to zero x=2 substitute 2³+2-10=0 8+2-10=0. (2³=2*2*2* =8) 10-10=0 ITS SO EASY 😂😂😂

Rational Root Theorem led me to one root quickly, factored that out, and got the two complex solutions. This one was a snap!
x^3 + x - 10 = x^3 - 2x^2 + 2x^2 - 4x + 5x - 10 = x^2(x-2) + 2x(x-2) + 5(x-2) = (x-2)(x^2 + 2x + 5) , so x=2 plus 2 complex roots

First method is more pain 😅
Есть корень 2, значит делить многочлен на Х - 2.
4:55 "and then a miracle occurs..."
😁
The second method is the distributive property in reverse.
synthetic division
Follow my move guys❤🎉🎉
First x=1,then
1³+1-10=0
1+1-10=0
2-10=0
Not equal to zero
x=2 substitute
2³+2-10=0
8+2-10=0. (2³=2*2*2*
=8)
10-10=0
ITS SO EASY 😂😂😂
Look at the thumbnail, factor out (x-2), then watch the video😉
