因式分解m²+2m(m-n)+(m-n)²,16-8(x-y)+(x-y)²因式分解m²+2m(m-n)+(m-n)²,16-8(x-y)+(x-y)

因式分解m²+2m(m-n)+(m-n)²,16-8(x-y)+(x-y)²
因式分解m²+2m(m-n)+(m-n)²,16-8(x-y)+(x-y)²

因式分解m²+2m(m-n)+(m-n)²,16-8(x-y)+(x-y)²
m²+2m(m-n)+(m-n)²
=(m+m-n)²
=(2m-n)²
16-8(x-y)+(x-y)²
=[4-(x+y)]²
=(4-x-y)²

m²+2m(m-n)+(m-n)²
=(m+m-n)²
=(2m-n)²

16-8(x-y)+(x-y)²
=[4-(x-y)]²
=(4-x+y)²
