Question

Bài 1: phân tích đa thức thành nhân tử.

b, 2xy+2xyz

d,27x^2+6x^2

f, (3x-6y)x+y(x-2y)

Answer 1

b) 2xy(1+z)

d) 33x^2

f) (x-2y)(3x+y)

Answer 2

b, 2xy+2xyz
=2xy(1+z)

d,27x^2+6x^2
=3x²(9+2)
=3x².11

f, (3x-6y)x+y(x-2y)
=3(x-2y)+y(x-2y)
=(3+y)(x-2y)

Answer 3

b: \(2xy+2xyz=2xy\left(z+1\right)\)

d: \(27x^2+6x^2=33x^2\)

f: \(\left(3x-6y\right)x+y\left(x-2y\right)=\left(x-2y\right)\left(3x+y\right)\)
