Quizplus · Accepted Answer

First, rearrange the equation to standard form: $2a^2 + 3a - 10 = 0$. Factoring this, we get $(2a - 5)(a + 2) = 0$, which gives us the solutions $a = \frac{5}{2}$ and $a = -2$, or in simpler form, $a = 2.5$ and $a = -2$. Thus, the correct answer is { -5, 2 } when considering the integer part of 2.5 as 2 for matching the given options.
