5(x-y)³ +10(y-x)² 因式分解.
5(x-y)³ +10(y-x)² 因式分解.
5(x-y)³ +10(y-x)² 因式分解.
原式=5(x-y)³+10(x-y)²
=5(x-y)²(x-y+2)
5(x-y)^3 +10(y-x)^2
=5{(x-y)^3 +2(x-y)^2}
=5(x-y)^2(x-y+2)
5(x-y)³ +10(y-x)²
5(x-y)²(x-y+2).
(x-y/x+2y)³
因式分解:x³+y³
说明理由(5x³-7x³y+3x³y)+2x³-(-7x³y+3x²y+7x³)的值与x、
(x+y)²-(x³+y³)÷(x+y)
5(x-y)³ +10(y-x)² 因式分解.
x³(x-2y)+y³(2x-y)
说明理由:多项式(5x³-7x³y+3x²y)+2x³-(+7x³+y3x²y+7x³)的值余x今晚就要 ,明天要交 .1.说明理由:多项式(5x³-7x³y+3x²y)+2x³-(+7x³+y3x²y+7x³)的
