Ответ:
a - 3 = (a - 3)(a + 3) / (a + 3) = (a^2 - 9) / (a + 3)
(-2√3a + 3) / (a - 3) = (-2√3a + 3) / [(a^2 - 9) / (a + 3)]
(-2√3a + 3) / [(a^2 - 9) / (a + 3)] * (a + 3) / (a + 3)
= (-2√3a + 3)(a + 3) / (a^2 - 9)
= (-2√3a^2 - 6√3a + 3a + 9) / (a^2 - 9)
= (-2√3a^2 - 6√3a + 3a + 9) / [(a - 3)(a + 3)]
= [-2a(√3a + 3) + 9] / [(a - 3)(a + 3)]
(-2a(√3a + 3) + 9) / [(a - 3)(a + 3)]
