Question

$2 {a}^{3} \sqrt(2 )+ 16 {b}^{3} + {c}^{3} - 12abc$
plz find this plzzzzzzz​

Answer 1

Answer:

Printing mistake .

Real question :

2√2a³ + 16√2b³ + c³ - 12 abc

Now , 2√2 = (√2)³ , 16√2 = (2√2)³

So :

(√2a)³ + (2√2b)³ + c³ - 3×2√2×2 × abc

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

= > (√2a+2√2b+c)(2a²+8b²+c²-4ab-2√2bc-√2ac)
