Question

x mũ 2 +2xy-3x-6y

Answer 1

rút gọn (2*x-6)*y+x^2-3*x

phân tích (x-3)*(2*y+x)

Answer 2

\(x^2+2xy-3x-6y=\left(x^2-3x\right)+\left(2xy-6y\right)=x\left(x-3\right)+2y\left(x-3\right)=\left(x-3\right)\left(x+2y\right)\)

Answer 3

x^2 + 2xy - 3x - 6y

= ( x^2 - 3x ) + ( 2xy - 6y )

= x ( x - 3 ) + 2y ( x - 3 )

= ( x - 3 ) ( x + 2y )
