1) 2x2 - 4x = 2x( x - 2 )
2) 3x - 6y = 3( x - 2y )
3) x2 - 3x = x( x - 3 )
4) 4x2 - 6x = 2x( x - 3 )
5) x3 - 4x = x( x2 - 4 ) = x( x - 2 )( x + 2 )
1) \(2x^2-4x=2x\left(x-2\right)\)
2) \(3x-6y=3\left(x-2y\right)\)
3) \(x^2-3x=x\left(x-3\right)\)
4) \(4x^2-6x=2x\left(2x-3\right)\)
5) \(x^3-4x=x\left(x-2\right)\left(x+2\right)\)
1, \(2x^2-4x=2x\left(x-2\right)\)
2, \(3x-6y=3\left(x-2y\right)\)
3, \(x^2-3x=x\left(x-3\right)\)
4, \(4x^2-6x=2x\left(x-3\right)\)
5, \(x^3-4x=x\left(x^2-4\right)=x\left(x-2\right)\left(x+2\right)\)
