Question

помогите пожалуйста....................​

Answer 1

$\frac{5 - 4t}{t {}^{2} - 6t } + \frac{4}{t - 6} = \frac{5 - 4t}{t \times (t - 6)} + \frac{4}{t - 6} = \frac{5 - 4t + 4t}{t \times (t - 6)} = \frac{5}{t {}^{2} - 6t }$

Answer 2

Объяснение:

$\frac{5 - 4t}{t {}^{2} - 6t} + \frac{4}{t - 6} =\frac{5-4t}{t\left(t-6\right)}+\frac{4}{t-6} =\frac{5-4t}{t\left(t-6\right)}+\frac{4t}{t\left(t-6\right)} =\frac{5-4t+4t}{t\left(t-6\right)} =\frac{5}{t\left(t-6\right)} =\frac{5}{t^{2}-6t}$
