Question

phân tích đa thức thành nhân tử
a)8x²y²-12x²y³³+20x³y³
b)6x(x-1)+8(1-x)
 

Answer 1

`a)8x^2y^2-12x^2y^3+20x^3y^3`

`=4x^2y^2(2-3y+5xy)`

_____________________________________

`b)6x(x-1)+8(1-x)`

`=6x(x-1)-8(x-1)`

`=(x-1)(6x-8)`

Answer 2

\(a,4x^2y^2\left(2-3y^{31}+5xy\right)\\ b,=6x\left(x-1\right)-8\left(x-1\right)\\ =\left(6x-8\right)\left(x-1\right)\)
