Question

3xy -y +3x^2 -x 

giúp mình với mấy bạn

Answer 1

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

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

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

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

Answer 2

3xy - y + 3x² - x

= ( 3xy - y ) + ( 3x² - x )

= y ( 3x - 1 ) + x ( 3x - 1 )

= ( y + x ) ( 3x - 1 )
