Answer 1

Răspuns:

$\frac{x + 5}{4} + \frac{x - 6}{2} \times \frac{2}{2} = \frac{x + 5 + 2x - 12}{4 } = \frac{3x - 7}{4}$

$\frac{ {(x + 4)}^{2} }{x(x + 4) } + \frac{( {x - 4)}^{2} }{x(x - 4)} = \frac{x + 4 + x - 4}{x} = 2$

$\frac{x - 4}{3(x + 2)} \times \frac{x}{x} + \frac{3x - 1}{x(x + 2)} \frac{3}{3} = \frac{ {x}^{2} - 4x + 9x - 3 }{ 3x(x + 2)} = \frac{ {x}^{2} + 5 x- 3 }{3x(x + 2)}$
