x^3 + 13x^2 + 32x + 20

》x^3 + 10x^2 + 3x^2 + 32x + 20

》x^2 ( x + 10 ) + 3x^2 + 32x + 20

》 x^2 ( x + 10 ) + 3x^2 + 30x + 2x + 20

》x^2 ( x + 10 ) + 3x ( x + 10 ) + 2x + 20

》x^2 ( x + 10 ) + 3x ( x + 10 ) + 2 ( x + 10 )

》( x + 10 )( x^2 + 3x + 2 )

》( x + 10 )( x^2 + 2x + x + 2 )

》( x + 10 )[ x ( x + 2 ) + 1 ( x + 2 ) ]
