(mx²+my²)²-4m²x²y²的分解因式
(mx²+my²)²-4m²x²y²
=(mx²)²+2m²x²y²+(my²)²-4m²x²y²
=(mx²)²-2m²x²y²+(my²)²
=(mx²-my²)²
=m²(x²-y²)²
=m²(x-y)²(x+y)²
=m²(x-y)(x-y)(x+y)(x+y)
(mx²+my²)²-4m²x²y²的分解因式
(mx²+my²)²-4m²x²y²
=(mx²)²+2m²x²y²+(my²)²-4m²x²y²
=(mx²)²-2m²x²y²+(my²)²
=(mx²-my²)²
=m²(x²-y²)²
=m²(x-y)²(x+y)²
=m²(x-y)(x-y)(x+y)(x+y)
