Answer:

 {(x + y + z)}^{2}  =  {x}^{2}  +  {y}^{2}  +  {z}^{2}   \\  +  2(xy + yz + xz)

answer = 4 {x}^{2}  + 9 {y}^{2}  + 16 {z}^{2}  \\  + 12xy + 24yz + 16xz

\begin{aligned}&(a+b+c)^{2}=a^{2}+b^{2}+c^{2}+2 a b+2 b c+2 {ca}\end{aligned}

a=2 x, b=3 y  , c=4 x  எனப் பிரதியிட

\begin{aligned}&((2 x)+(3 y)+(4 z))^{2}=(2 x)^{2}+(3 y)^{2}+(4 z)^{2}+2(2 x)(3 y)+2(3 y)(4 z)+2(4 z)(2 x)\end{aligned}

                                 \begin{aligned}&=4 x^{2}+9 y^{2}+16 z^{2}+12 x y+24 y z+16 x z\end{aligned}.
