Question

a) 3x²- 6x         b) 2xy+2xyz     c) 15x²y - 9x²y²    d) 27x³ +6x²

e) 2x² (x - 3) - x (x - 3)    f) (3x - 6y)x + y(x - 2y)

LM NHANH LÊN ĐC K❗❗

Answer 1

\(a)3x^2-6x=3x(x-2)\)

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

\(c)15x^2y-9x^2y^2=3xy(5x-3xy)\)

\(d)27x^3+6x^2=3x^2(9x+2)\)

\(e)2x^2(x-3)-x(x-3)=(x-3)(2x^2-x)\)

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

Answer 2

a: =3x(x-2)

b: =2xy(1+z)

c: =3x^2y(5-3y)

d: \(=3x^2\left(9x+2\right)\)

e: \(=x\left(x-3\right)\left(2x-1\right)\)

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

Answer 3

a,3x(x-2)

b,2xy(1+z)

c,\(3x^2y\left(5-3y\right)\)

d,\(3x^2\left(9x+2\right)\)

e,\(x\left(x-3\right)\left(2x-1\right)\)

f,(x−2y)(3x+y)
