b,9x mũ 2 y mũ 2+3x mũ 2+6x mũ 2 y
c,-12x mũ 2 y+36xy+24xy mũ 2
d,2x(x-y)+(x-y)
e,4x mũ 2(x-y)-8x(y-x)
f,6ax mũ 2(x-3y)+2ax(3y-x)
mn giúp mik vs ạ mik đag cần gấp ạ

 

Answer 1

a, \(8x^3y+4x^2y^3=4x^2y\left(2y^2+y^3\right)\)

b, \(9x^2y^2+3x^2+6x^2y=3x^2\left(3y^2+1+2y\right)\)

c, \(-12x^2y+36xy+24xy^2=-12xy\left(x-3-2y\right)\)

d, \(=\left(2x+1\right)\left(x-y\right)\)

e, \(=\left(4x^2+8x\right)\left(x-y\right)=4x\left(x+2\right)\left(x-y\right)\)

f, \(=\left(6ax^2-2ax\right)\left(x-3y\right)=2ax\left(3x-1\right)\left(x-3y\right)\)
