分解因式;(x+5y)^2+(2x+10y)(3x-y)+(3x-y)^2
分解因式;(x+5y)^2+(2x+10y)(3x-y)+(3x-y)^2

分解因式;(x+5y)^2+(2x+10y)(3x-y)+(3x-y)^2
(x+5y)^2+(2x+10y)(3x-y)+(3x-y)^2
=(x+5y)^2+2(x+5y)(3x-y)+(3x-y)^2
=(x+5y+3x-y)^2
=16(x+y)^2
肯定对

(x+5y)^2+(2x+10y)(3x-y)+(3x-y)^2
=(x+5y)^2+2(1x+5y)(3x-y)+(3x-y)^2
=[(x+5y)+(3x-y)]^2
=(4x+4y)^2
=16(x+y)^2

=(x+5y)^2+2(x+5y)(3x-y)+(3x-y)^2=(x+5y+3x-y)^2=(4x+4y)^2=16(x+y)^2

=(x+5y)²+2(x+5y)(3x-y)+(3x-y)²=(x+5y+3x-y)² =(4x+4y)² =16(x+y)²

=[(x+5y)+(3x-y)]²
=16(x+y)²
把(x+5y)和(3x-y)看成是完全平方公式的A项和B项,然后用完全平方和公式解即可。
