Question

Phân tích đa thức thành nhân tử 4x^2-8x+3

 

Answer 1

4x² - 8x + 3

= 4x² - 6x - 2x + 3

= ( 4x² - 6x ) - ( 2x - 3 )

= 2x( 2x - 3 ) - ( 2x - 3 )

= ( 2x - 3 )( 2x - 1 )

Answer 2

\(4x^2-8x+3\)

\(=4x^2-2x-6x+3\)

\(=\left(4x^2-6x\right)-\left(2x-3\right)\)

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

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

Answer 3

Bài làm 

\(4x^2-8x+3=4x^2-2x-6x+3\)

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