Djamila is looking for conjugate pair solutions to the equation 3x2−5x=−6. Which of the following options should she choose?(1 point)

1 answer

To find the conjugate pair solutions to the equation \(3x^2 - 5x = -6\), we first rearrange the equation into standard quadratic form:

\[ 3x^2 - 5x + 6 = 0. \]

Next, we can use the quadratic formula to find the roots of the equation, where \(a = 3\), \(b = -5\), and \(c = 6\). The quadratic formula is given by:

\[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}. \]

Let's calculate the discriminant \(D = b^2 - 4ac\):

\[ D = (-5)^2 - 4 \cdot 3 \cdot 6 = 25 - 72 = -47. \]

Since the discriminant is negative (\(D < 0\)), the solutions will be complex (conjugate pair solutions).

Now, we can compute the roots using the quadratic formula:

\[ x = \frac{5 \pm \sqrt{-47}}{2 \cdot 3} = \frac{5 \pm i\sqrt{47}}{6}. \]

This gives us the conjugate pair solutions:

\[ x_1 = \frac{5 + i\sqrt{47}}{6}, \quad x_2 = \frac{5 - i\sqrt{47}}{6}. \]

If options were provided, Djamila should choose the one that corresponds to these conjugate pair solutions. If you have specific options to consider, please let me know!
