Question

Faktorkanlah, pake caranya ya makasih :)

Answer 1

(x-y)² + 3(y - x)³
=> (x - y)(x - y) + 3(y - x)(y - x)(y - x)
=> [x² - xy - xy + y²] + 3(y - x)[y² - xy - xy + x²]
=> (x² - 2xy + y²) + 3(y - x)(x² - 2xy + y²)
=> (x² - 2xy + y²)[1 + 3(y - x)]
=> (x² - 2xy + y²)(1 + 3y - 3x)

Answer 2

(x - y)² + 3(y - x)³
x² -2xy + y² + 3 (y³ - 3y²x + 3yx² -x²)
x² - 2xy + y² + 3y³ - 9y²x + 9yx² - 3x³
