Answer:

x + 2y + 3z = 0

2y + 3z = - x -- equation (1)

x + 2y = - 3z -- equation (2)

x + 3z = - 2y -- equation (3).

Also given that,

x³ + 4y³ + 9z³ = 18xyz

⟹ (x³ + 4y³ + 9z³)/xyz = 18 -- equation (4)

We have to find:-

\implies \sf \: \dfrac{(x + 2y) ^{2} }{xy} + \dfrac{(2y + 3z) ^{2} }{yz} + \dfrac{(3z + x) ^{2} }{xz} ⟹

xy

(x+2y)

2

+

yz

(2y+3z)

2

+

xz

(3z+x)

2

Putting the respective values from equations (1) , (2) & (3) we get,

\implies \sf \: \dfrac{( - 3z) ^{2} }{xy} + \dfrac{( - x) ^{2} }{yz} + \dfrac{( - 2y) ^{2} }{xz} ⟹

xy

(−3z)

2

+

yz

(−x)

2

+

xz

(−2y)

Taking LCM we get,

\begin{gathered} \implies \sf \: \dfrac{(yz)(xz)(9 {z}^{2} ) +(xy)(xz)(x ^{2} ) + (xy)(yz)( 4y ^{2} )}{xy \times yz \times xz} \\ \\ \\ \implies \sf \: \dfrac{ 9xy {z}^{4} + {x}^{4}yz + 4xy ^{4}z }{(xyz) ^{2} } \\ \\ \\ \implies \sf \: \frac{xyz( 9 {z}^{3} + {x}^{3} + 4y ^{3} ) }{(xyz)(xyz)} \\ \\ \\ \implies \sf \: \frac{ {x}^{3} + 4 {y}^{3} + 9 {z}^{3} }{xyz} \\ \\ \\ \implies \underline{ \underline{ \red{\sf \: 18}}} \: \: \: \: \: \sf \: [ \because \: from \: equation \: (4)]\end{gathered}
