[@freddyalvaradamaranon304]

Interesante ejercicio y muy didáctica la explicación, mi hija y mi persona estamos muy agradecidos por compartir tan buena clase. Bendiciones y saludos Profesor Tambuwal. 😊

The four 4th roots of unity are 1, i, -1, and -i. Thus 2x-1 is equal to these four roots. x=(1+1)/2=1, x=(1+i)/2, x=(1-1)/2=0, and x=(1-i)/2

I know, but as a teacher you have to show why the fourth root of 1 gives the four values

Great one. i hope to grow my influence too

[@seropgh4781]

X can also be just one you know just 4th root both sides

[@hamadijawo4068]

I don't understand the i? Where you have (_1)^2

1) ( 2X-1)² * ( 2X-1)² = 1 2) (4X² + 1 - 4X) * (4X² + 1 - 4X) = 1 *** 4X² + 1 - 4X = 1 4X² - 4X = zero X = 1 ; X = 0 ; * I know that there are two other roots (+ or - i), but they are imaginary numbers that do not apply to our practical world on a daily basis, only for complex calculations!!!!
