विस्तार सूत्र:

 {(x + y + z)}^{2}  =  {x}^{2}  +  {y}^{2}  +  {z}^{2}  + 2xy + 2yz + 2xz \\  \\
x = m \\  \\ y = 2n \\  \\ z = 3r \\  \\
 {(m + 2n +3r )}^{2}  =  {m}^{2}  +  {(2n)}^{2}  +  {(3r)}^{2}   \\  \\ + 2(m)(2n) + 2(2n)(3r) + 2(m)(3r) \\  \\  =  {m}^{2}  + 4 {n}^{2}  + 9 {r}^{2}  + 4mn + 12nr + 6mr \\  \\
विस्तार:

 {(m + 2n +3r )}^{2} = {m}^{2}  + 4 {n}^{2}  + 9 {r}^{2}  + 4mn + 12nr + 6mr \\  \\
