Question

como resolver (x/2+y/2)²

Answer 1

$( \dfrac{x}{2} + \dfrac{y}{2} )^{2} = ( \dfrac{x}{2} )^{2} +2. \dfrac{x}{2} . \dfrac{y}{2} + ( \dfrac{y}{2} )^{2} = \dfrac{ x^{2} }{4} +\dfrac{xy}{2} + \dfrac{ y^{2} }{4}= \dfrac{ x^{2} +2xy+ y^{2} }{4}$

Answer 2

$( \frac{x}{2} + \frac{y}{2} ) {}^{2} \\ \frac{ {(x}^{} + y^{} ) {}^{2} }{2} \\ \\ \frac{x {}^{2} +2 \times x \times y + {y}^{2} }{4} \\ \frac{ {x}^{2} + 2xy + {y}^{2} }{4}$
