4(x-y)²-25(x+y)²=[2(x-y)]2-[5(x+y)]2=[2(x-y)+
5(x+y)][ 2(x-y)- 5(x+y)]=(7x+3y)(-3x-7y)
5(x+y)][ 2(x-y)- 5(x+y)]=(7x+3y)(-3x-7y)

4(x-y)²-25(x+y)²=-(3x+7y)(7x+3y)
解:
4(x-y)²-25(x+y)²
=[2(x-y)]²-[5(x+y)]²
=[2(x-y)-5(x+y)][2(x-y)+5(x+y)]
=(-3x-7y)(7x+3y)
=-(3x+7y)(7x+3y)
解:
4(x-y)²-25(x+y)²
=[2(x-y)]²-[5(x+y)]²
=[2(x-y)-5(x+y)][2(x-y)+5(x+y)]
=(-3x-7y)(7x+3y)
=-(3x+7y)(7x+3y)
