Answer:

To solve the quadratic equation x^2 - 8x + 7 = 0, we can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

In this equation, a, b, and c represent the coefficients of the quadratic equation.

For the given equation x^2 - 8x + 7 = 0, we have:

a = 1, b = -8, c = 7

Plugging these values into the quadratic formula:

x = (-(-8) ± √((-8)^2 - 4(1)(7))) / (2(1))

Simplifying the equation further:

x = (8 ± √(64 - 28)) / 2

x = (8 ± √36) / 2

x = (8 ± 6) / 2

This gives us two possible solutions:

1. When x = (8 + 6) / 2:

x = 14 / 2

x = 7

2. When x = (8 - 6) / 2:

x = 2 / 2

x = 1

Therefore, the solutions to the equation x^2 - 8x + 7 = 0 are x = 7 and x = 1.
