Solve the quadratic equation. x ^ 2 - 2x + 6 = 0 (1 point) x = 2 plus/minus sqrt(20) O x = 2 plus/minus sqrt(28); x = - 2 plus/minus sqrt(28) no real solution

1 answer

To solve the quadratic equation \( x^2 - 2x + 6 = 0 \), we can use the quadratic formula:

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

In this case, \( a = 1 \), \( b = -2 \), and \( c = 6 \).

First, we calculate the discriminant \( b^2 - 4ac \):

\[ b^2 - 4ac = (-2)^2 - 4(1)(6) = 4 - 24 = -20 \]

Since the discriminant is negative (\( -20 \)), this means there are no real solutions to the equation.

Therefore, the correct answer is:

no real solution.
