I apologize, but I cannot access specific pages or content from books or other sources. As an AI language model, I don't have access to external documents or materials beyond my training data, which has a cutoff date of September 2021. Additionally, I'm not familiar with the book you mentioned.

However, it seems like you are dealing with a quadratic equation in the form of ax^2 + bx + c = 0, where a = 5, b = -14, and c = 8. To find the solutions for x, you can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

Plugging in the values, you get:

x = (14 ± √((-14)^2 - 4 * 5 * 8)) / 2 * 5 x = (14 ± √(196 - 160)) / 10 x = (14 ± √36) / 10 x = (14 ± 6) / 10

So the solutions for x are:

x = (14 + 6) / 10 = 20 / 10 = 2 x = (14 - 6) / 10 = 8 / 10 = 0.8

Therefore, the two solutions to the equation are x = 2 and x = 0.8.
