Answer 2

Answer:

To begin with the answer, you need to remember a formula :-

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

Therefore,

(2x+3y+4z) =

${(2x)}^{2} + {(3y)}^{2} + {(4z)}^{2} + 2(2x \times 3y + 3y \times 4z + 2x \times 4z)$

=

${4x}^{2} + {9y}^{2} + {16z}^{2} + 2(6xy + 6yz + 4xz)$

=

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

Hope it helps :)
