✔ 最佳答案
= 12x³y - 24xy³= 12xy(x² - 2y²)
Answer: 12x(x² - 2y²)

12x³y - 24xy³ = 12xy(x² - 2y²)
2009-03-04 2:26 pm
12x^3y - 24xy^3
= 12(x^3y - 2xy^3)
= 12xy(x^2 - 2y^2)
= 12(x^3y - 2xy^3)
= 12xy(x^2 - 2y^2)

12x3y - 24xy^3 = 36xy - 24xy^3 = 12xy ( 3 - 2y^2 ) ... but, I suspect that what you meant was:
12x^3y - 24xy^3 nicht war ?
In which case we have:
12x^3y - 24xy^3 = 12xy ( x^2 - 2y^2 )
Alors !
12x^3y - 24xy^3 nicht war ?
In which case we have:
12x^3y - 24xy^3 = 12xy ( x^2 - 2y^2 )

12x3y-24xy^3 = 12xy (x^2 - 2y^2)

-12xy(2y^2-3)

12x³ y-24xy³
=12xy(x² −2y² )=12xy{(x)² −(√2y)² }
=12xy(x+√2y)(x−√2y)
=12xy(x² −2y² )=12xy{(x)² −(√2y)² }
=12xy(x+√2y)(x−√2y)

36xy - 24xy^3 = 12xy(3-2y^2)
