-8a³b²+12ab³c-6a²-6a²b
=-2(4a³b²-6ab³c+3a²+3a²b)
3a(x-y)+9(y-x)
=3a(x-y)-9(x-y)
=3(x-y)(a-3)
(2m-3n)²-2m+3n
=(2m-3n)²-(2m-3n)
=(2m-3n)(2m-3n-1)
16mn⁴-m
=m(16n⁴-1)
=m(4n²+1)(4n²-1)
=m(4n²+1)(2n+1)(2n-1)
=-2(4a³b²-6ab³c+3a²+3a²b)
3a(x-y)+9(y-x)
=3a(x-y)-9(x-y)
=3(x-y)(a-3)
(2m-3n)²-2m+3n
=(2m-3n)²-(2m-3n)
=(2m-3n)(2m-3n-1)
16mn⁴-m
=m(16n⁴-1)
=m(4n²+1)(4n²-1)
=m(4n²+1)(2n+1)(2n-1)
