因式分解3(y-2)2-(2y-z)(-z+2y)还有【x(x²y²-xy)-y(x²-x³y)】除以3x²y因式分解3(y-2)2-(2y-z)(-
因式分解 3(y-2)2-(2y-z)(-z+2y)还有【x(x²y²-xy)-y(x²-x³y)】除以3x²y
因式分解 3(y-2)2-(2y-z)(-z+2y)
还有【x(x²y²-xy)-y(x²-x³y)】除以3x²y
因式分解 3(y-2)2-(2y-z)(-z+2y)还有【x(x²y²-xy)-y(x²-x³y)】除以3x²y
【x(x²y²-xy)-y(x²-x³y)】除以3x²y
=[x²y(xy-1)+x²y(xy-1)]/3x²y
=2(xy-1)/3
