Question

Phân tích đa thức thành nhân tử 

2x - 3x² + x 

Answer 1

\(2x-3x^2+x\)

\(=x\left(2-3x+1\right)\)

\(=x\left(-3x+3\right)\)

\(=-3x\left(x-1\right)\)

Answer 2

2x - 3x² + x 

=x.(2-3x+1)

=x.(3-3x)

=x.(3.(1-x))

=3x.(1-x)

Answer 3

2x-3x²+x

=(-3)(x-1)x

Answer 4

2x - 3x² + x 

=x.(2-3x+1)

=x.(3-3x)

=x.(3.(1-x))

=3x.(1-x)

Answer 5

2x - 3x² + x 

=x.(2-3x+1)

=x.(3-3x)

=x.(3.(1-x))

=3x.(1-x)

Answer 6

2x - 3x²+x

=(-3)(x-1)x

=???

Answer 7

\(2x-3x^2+x=x\left(2-3x+1\right)=x\left(-3x+3\right)=-3x\left(x-1\right)=3x\left(1-x\right)\)

Answer 8

Ta có : 2x-3x²+x

=x(2-3x+1)

=x(3-3x)

=3x(1-x)

Answer 9

\(\)2x-3x²+x=x.(2-3x+1)

              =x.(3-3x)

              =3x.(1-x)
