(-4x(2xy+3xy^2)+12(x^2y)^2y^3)÷(-6xy)
(-4x(2xy+3xy^2)+12(x^2y)^2y^3)÷(-6xy)
(-4x(2xy+3xy^2)+12(x^2y)^2y^3)÷(-6xy)
原式=[-4x(2xy+3xy²)+12(x²y)²y³]÷(-6xy)
=[-4x×2xy-4x×3xy²+12×(x²)²×y²×y³]÷(-6xy)
=(-8x²y-12x²y²+12x^4y^5)÷(-6xy)
=-8x²y÷(-6xy)-12x²y²÷(-6xy)+12x^4y^5÷(-6xy)
=-8÷(-6)×(x²÷x)×(y÷y)-12÷(-6)×(x²÷x)×(y²÷y)+12÷(-6)×(x^4÷x)×(y^5÷y)
=(4/3)x+2xy-2x³y^4
3xy(x^2-xy^2+xy)-xy^2(2x^2-xy+2x)
xy-2{xy-[3x^2y-(4xy^2+0.5xy)]+4x^2y}+6xy^2
(X-3xy+4xy-y)-[-2x-2(xy-3/2xy)-y]+6xy的过程
-3(2x^2-xy)+4(x^2+xy-6)
(-3x^y+2xy)-( )=4x^+xy
4(x²+xy-6)-3(2x²-xy)
-3(2x²-xy)+4(x²+xy-6)
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
化简:3x^2-[5xy-(x^y-3xy)+4x^2y-8xy]
因式分解X^3-2xy+xy^2
化简:-x(2)-(2xy) *9x(2)-9xy(3)+12x(4)y(2)/(3xy)谢谢!
2x²y-3(2xy-xy)-xy
(-3xy+2xy)-(4xy+xy)
12xy+(3x平方-5xy)-2(3xy+2x平方)计算
x^3y(-4y)^2+(-7xy)^2*(-xy)-5xy^3*(-3x)^2
5x^3y*(-3y)^2+(-6xy)^2*(-xy)+xy^3*(-4x^2)
