Ghi đoạn giúp mik nha

hi nho

Hello Yen, my name is Uyen. Nice to meet you!

my name is meo meo.nice to meet you

\(x^3 - y^3 - 4x + 4y = (x^3 - y^3) - (4x - 4y)\)

\(= (x - y)(x^2 + xy + y^2) - 4(x - y)\)

\(= (x - y)(x^2 + xy + y^2 - 4)\)

\((x - y)(x^2 + xy + y^2 - 4)\)

x³ - y³ - 4x + 4y
= (x³ - y³) - (4x - 4y)
= (x - y)(x² + xy + y²) - 4(x - y)
= (x - y)(x² + xy + y² - 4)
