is your answer for this q

Answer 2

Answer:

$( \frac{x}{2} + \frac{y}{3} + \frac{z}{2} )^{2} \\ = {( \frac{x}{2} )}^{2} + {( \frac{y}{3} )}^{2} + {( \frac{z}{2} )}^{2} \\ + 2 \times \frac{x}{2} \times \frac{y}{3} + 2 \times \frac{y}{3} \times \frac{z}{2} \\ + 2 \times \frac{x}{2} \times \frac{z}{2} \\ = \frac{ {x}^{2} }{4} + \frac{ {y}^{2} }{9} + \frac{ {z}^{2} }{4} + \frac{xy}{3} + \frac{yz}{3} + \frac{xz}{2}$
