Question

решите
$\frac{x {}^{2} + 0.5x - 13 }{x {}^{2} - 0.5x \times 14 }$

Answer 1

$\frac{ x^{2}+0.5x-13 }{ x^{2} -0.5x*14} \\ \\ \frac{ x^{2} + \frac{1}{2}x-13 }{ x^{2} -7x} \\ \\ \frac{2 x^{2} +x-26}{2} \\ x^{2} -7x\\ \\ \frac{2 x^{2} +x-26}{2 (x^{2} -7x)}\\ \\ \frac{2 x^{2} +x-26}{2 x^{2} -14x}$
