1. The problem is to simplify and solve the expression $$x = \frac{-(-5) + \sqrt{(-5)^2 - 4(2)(6)}}{2(2)}$$.
2. First, simplify the numerator's components:
- The double negative: $-(-5) = 5$
- Calculate inside the square root: $$(-5)^2 = 25$$
- Calculate the product inside the square root: $$4 \times 2 \times 6 = 48$$
3. Substitute these values back into the expression under the square root:
$$\sqrt{25 - 48} = \sqrt{-23}$$
4. Since the square root of a negative number involves imaginary numbers, rewrite it as:
$$\sqrt{-23} = i\sqrt{23}$$ where $i$ is the imaginary unit.
5. Now the expression becomes:
$$x = \frac{5 + i\sqrt{23}}{4}$$
6. This is the simplified form of $x$ in terms of real and imaginary parts.
Final answer:
$$x = \frac{5}{4} + \frac{i\sqrt{23}}{4}$$
