Answer 1

Resposta:

Resposta:

$(x + \frac{1}{2} ) \times (x - \frac{1}{2} ) + \frac{3}{4} \\ (\frac{2x + 1}{2} )\times (\frac{2x - 1}{2} )+ \frac{3}{4} \\ \frac{4 {x}^{2} - 2x + 2x - 1 }{4} + \frac{3}{4} \\ \frac{4 {x}^{2} - 1}{4} + \frac{3}{4} = \frac{16 {x}^{2} - 4 + 12 }{16} \\ \frac{16 {x}^{2} + 8}{16} = {x}^{2} + \frac{1}{2}$
