x 2 − 8 x + 19 = x 2 − 8 x + 16 + 3 = ( x − 4 ) 2 + 3 ( x − 4 ) 2 + 3 = 0 ( x − 4 ) 2 = − 3 x ∈ ∅
To solve the equation x 2 − 8 x + 19 = 0 , we use the quadratic formula, which results in complex solutions due to a negative discriminant. The solutions are x = 4 + 3 i and x = 4 − 3 i . Therefore, this equation does not have any real solutions.
