a的2次方(x-y)+16(y-x)因式分解a的2次方(x-y)+16(y-x)因式分解a的2次方(x-y)+16(y-x)因式分解a的2次方(x-y)+16(y-x)=a的2次方(x-y)-16(x

a的2次方(x-y)+16(y-x)因式分解
a的2次方(x-y)+16(y-x)因式分解

a的2次方(x-y)+16(y-x)因式分解
a的2次方(x-y)+16(y-x)
=a的2次方(x-y)-16(x-y)
=(x-y)(a²-16)
=(x-y)(a+4)(a-4)

a的2次方(x-y)+16(y-x)
=a的2次方(x-y)-16(x-y)
=(a²-16)(x-y)
=(a+4)(a-4)(x-y)
