x^2-6xy+9y^2-2x+6y-3因式分解
x^2-6xy+9y^2-2x+6y-3因式分解
x” - 6xy + 9y" - 2x + 6y - 3
= x” - 2x(3y) + (3y)” - 2x + 6y - 3
= ( x - 3y )" - 2( x - 3y ) + 1 - 4
= ( x - 3y + 1 )” - 2”
= ( x - 3y + 1 - 2 )( x - 3y + 1 + 2 )
= ( x - 3y - 1 )( x - 3y + 3 )
化简:x-y/x+3y÷x^-y^2/x^2+6xy+9y^2-(xy/x+y)
(x-2xy)*(-xy+2y*y)-(3x*x-2xy)(x-9xy+6y*y)答案应为-2x-x*x-3x,
1、(-7x^y)(2x^y-3xy^3+xy) 2、((x-y)^6)/((y-x)^3)/(x-y)
