Question

Упрости выражение
$\frac{7}{ \beta - 13} + \frac{2}{ \beta }$
​

Answer 1

Объяснение:

$\frac{7}{ \beta - 13} + \frac{2}{ \beta } = \frac{7 \beta + 2( \beta - 13)}{ \beta \times ( \beta - 13)} = \frac{7 \beta + 2 \beta - 26}{ \beta {}^{2} - 13 \beta } = \frac{9 \beta - 26}{ \beta {}^{2} - 13 \beta }$
