To find the conjugate pair solutions for the equation \( x^2 - 3x + 8 = -2 \), we should first rearrange the equation to standard form:
\[ x^2 - 3x + 10 = 0 \]
Next, we can use the quadratic formula, which is given by:
\[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \]
In this case, \( a = 1 \), \( b = -3 \), and \( c = 10 \). First, we calculate the discriminant:
\[ b^2 - 4ac = (-3)^2 - 4(1)(10) = 9 - 40 = -31 \]
Since the discriminant is negative, we will have complex solutions. Now we can continue applying the quadratic formula:
\[ x = \frac{-(-3) \pm \sqrt{-31}}{2(1)} = \frac{3 \pm i\sqrt{31}}{2} \]
Thus, the solutions are:
\[ x = \frac{3}{2} \pm \frac{i\sqrt{31}}{2} \]
So the correct answer that shows the conjugate pair solutions is:
\[ \frac{3}{2} \pm \frac{i \sqrt{31}}{2} \]
