Which method did you use for turning 1+x^3 to (1+x)^3-3x(1+x)
(x+1)^3= x^3 + 3x^2 + 3x + 1 thenx^3 +1 = (x+1)^3 - 3X^2 - 3x thenx^3 +1 = (x+1)^3 - 3x( x+1)
shouldnt it be x=-2 |+ or -| (sqrt(3))/2?
what do you mean this is "olympiad level" math in the video tags I could solve this using the polynomial factor
That’s impressive! If you solved it using the polynomial factor, great work! The 'Olympiad level' tag just indicates the type of approach or problem-solving style used in the video.
