Pl help fast The quadratic function y = -x2 + 10x - 8 models the height of a trestle on a bridge. The x-axis represents ground level.

To find where the section of the bridge meets ground level, solve 0 = -x2 + 10x - 8.

Where does this section of the bridge meet ground level?

Choose an equation that would be used to solve 0 = -x2 + 10x – 8

(x + 25)2 = –8

(x – 5)2 = 17

(x – 10)2 = 25
