Question

factorise - 8xcube +ycube+27zcube-3xyz​

Answer 1

Step-by-step explanation:

8x³ +y³+27z³-3xyz

here we can use Identity:

x³+y³+z³-3xyz= (x+y+z)(x²+y²+z²-xy-yz-zx)

(2x)³+y³+(3z)³-3xyz= (2x+y+3z)(4x²+y²+9z²-2xy-3yz-6xz)

so, the factorized form will be :

(2x+y+3z)(4x²+y²+9z²-2xy-3yz-6xz)

hope it will help u

have a good day ahead
