1-(x^2+10xy+25y^2)因式分解1-(x^2+10xy+25y^2)因式分解1-(x^2+10xy+25y^2)因式分解1-(x^2+10xy+25y^2)=1-(x+5y)^2=(1+x

1-(x^2+10xy+25y^2)因式分解
1-(x^2+10xy+25y^2)因式分解

1-(x^2+10xy+25y^2)因式分解
1-(x^2+10xy+25y^2)
=1-(x+5y)^2
=(1+x+5y)(1-x-5y)

1-(x^2+10xy+25y^2)
=1- (x+5y)^2
=(1-x-5y)(1+x+5y)

后面x^2+10xy+25y^2可以化简成(x+5y)^2
1-(x+5y)^2就用平方差公式,得(1+x+5y)(1-x-5y)
