分解因式:6(x-2y)^2-2x(2y-x)

分解因式:6(x-2y)^2-2x(2y-x)
分解因式:6(x-2y)^2-2x(2y-x)

分解因式:6(x-2y)^2-2x(2y-x)
答:
6(x-2y)^2-2x(2y-x)
=6(x-2y)^2+2x(x-2y)
=2(x-2y)*[3(x-2y)+x]
=2(x-2y)(4x-6y)
=4(x-2y)(2x-3y)

=(6x-12y)(x-2y)+2x(x-2y)=(8x-12y)(x-2y)=2(4x-3y)(x-2y)

解:原式=2[(x-2y)^2-x(2y-x)]=2[(x-2y^2)+x(x-2y)]=2(x-2y)(2x-2y)=4(x-2y)(x-y)

6(x-2y)^2-2x(2y-x)
=6x^2-24xy+24y^2-4xy+2x^2
=8x^2-28xy+24y^2
=4(2x-3y)(x-2y)

=6(x^2-4xy+4y^2)-4xy+2x^2
=6x^2-24xy+24y^2-4xy+2x^2
=8x^2-28xy+24y^2
4(2x-3y)(x-2y)

6(x-2y)²-2x(2y-x)
=6(x-2y)²+2x(x-2y)
=2(x-2y)[3(x-2y)+x]
=2(x-2y)(4x-6y)
=4(x-2y)(2x-3y)
