Djamila is looking for conjugate pair solutions to the equation 3x^2 - 5x = -6. Which of the following options should she choose?

5/6 ± i√47/6

5/6 ± 5i/6

-5/6 ± i√47/6

5/6 ± 7i/6

1 answer

To find the conjugate pair solutions to the equation, we need to find the roots of the equation. To start, we can rearrange the equation into the standard quadratic form:

3x^2 - 5x + 6 = 0

To solve this quadratic equation, we can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

In this case, a = 3, b = -5, and c = 6.

x = (-(-5) ± √((-5)^2 - 4(3)(6))) / (2(3)) = (5 ± √(25 - 72)) / 6 = (5 ± √(-47)) / 6

Since we have a square root of a negative number, we know that the solutions will be complex numbers and will have conjugate pairs.

Therefore, Djamila should choose the option 5/6 ± i√47/6 as the correct answer, as it represents the conjugate pair solutions to the equation.
