1) \(6a^2-3a+12ab=3\left(2a^2-a+6ab\right)\)
2) \(2x^2y^4-2x^4y^2+6x^3y^3=2x^2y^2\left(y^2-x^2+3xy\right)\)
3) \(5x^2+10xy+5y^2=5\left(x^2+2xy+y^2\right)=5\left(x+y\right)^2\)
4) \(4y^2-\left(y-m\right)^2=\left(2y+y-m\right)\left(2y-y+m\right)=\left(3y-m\right)\left(y+m\right)\)
5) \(8m^3+12m^2+6m+1=\left(2m+1\right)^3\)
1)6a2-3a+12ab
=3a(4b+12a-1)
2)2x2y4-2x4y2+6x3y3
=2x2y2(y2+3xy-x2)
3)5x2+10xy+5y2
=5(x2+5xy+y2)
=5(x+y)2
4)4y2-(y-m)2
=4y2-y2+2my-m2
=4y2-my+3my-m2
=y(3y-m)+m(3y-m)
=(y+m)(3y-m)
5)sai đề
