-9y^2+6xy-x^2
-9y^2+6xy-x^2
-9y^2+6xy-x^2
-9y^2+6xy-x^2=-(9y^2-6xy+x^2)=-(3y-x)²
-(3y-x)²
(x-2xy)*(-xy+2y*y)-(3x*x-2xy)(x-9xy+6y*y)答案应为-2x-x*x-3x,
化简:x-y/x+3y÷x^-y^2/x^2+6xy+9y^2-(xy/x+y)
(9x^2y-6xy^2)/3xy
[ 2x-6y][8-9xy]÷xy等于?
-9y^2+6xy-x^2
x^2-xy-6y^2+3xy+y+2
-3x^2y+6xy^2-9xy=( )(x-2y+3)
①(9x²y-6xy²)÷3xy ②(3x²y-xy²+2分之1xy)÷(-2分之1xy)
xy-2{xy-[3x^2y-(4xy^2+0.5xy)]+4x^2y}+6xy^2
