how to solve?
Which of the following is a solution to the equation x2 – 6x + 5 = 0?
A. x = -5
B. x = -1
C. x =
D. x = 5
x^2 – 6x + 5 = 0
x^2 – 6x = - 5
x^2 - 6x + 3^2 = -5 + 3^2
(x - 3)(x - 3) = -5 + 9 = 4
x - 3 = √4
x - 3 = ±2
x = ±2 + 3
x = 2 + 3 and x = -2 + 3
x = 5 and x = 1
The only one in the list is D. 5
