Question

Factorise 2root 2a cube +8b cube -27c cube +18root 2abc

Answer 1

Answer:You can see answer down.

Step-by-step explanation:

2√2a^3+8b^3-27c^3+18√2abc

=(√2a)^3+(2b)^3+(-3c)^3-3(√2a)(2b)(-3c)

=(√2a+2b-3c)(2a^2+4b^2-9c^2-2√2ab+6bc+3√2ac)

{a^3+b^3+c^3-3abc=(a+b+c)(a^2+b^2+c^2-ab-bc-ca) }
