Question

Виконайте додавання a+1/3a-15 + a-1/2a-10

Answer 1

Объяснение:

$\frac{a + 1}{3a - 15} + \frac{a - 1}{2a - 10} = \frac{a + 1}{3(a - 5)} + \frac{a - 1}{2(a - 5)} = \frac{2(a + 1)}{6(a - 5)} + \frac{3(a - 1)}{6(a - 5)} = \frac{2(a + 1) + 3(a - 1)}{6(a - 5)} = \frac{2a + 2 + 3a - 3}{6(a - 5)} = \frac{5a - 1 }{6(a - 5)}$
