因式分解:-6a^3b^2 4ab^3c-2a^2b
问题描述:
因式分解:-6a^3b^2 4ab^3c-2a^2b
(x-y)^2-x+y
25(a+b)^2-4(a-b)^2
a^5b-ab^5
x^2-10x+25
3a^2-6a^2b+2ab
3x(a-b)-6y(b-a)
(x^2+4)^2-16x^2
答
( x - y )" - x + y= ( x - y )" - ( x - y )= ( x - y )( x - y - 1 ) 25( a + b )" - 4( a - b )"= [ 5( a + b ) ]" - [ 2( a - b ) ]"= [ ( 5a + 5b ) + ( 2a - 2b ) ][ ( 5a + 5b ) - ( 2a - 2b ) ]= ( 7a + 3b ...还有第一个,
-6a"'b" + 4ab"'c - 2a"b
= ( -2ab )( 3a"b - 2b"c + a )
