    for the other zeros, don't you have to solve for x^2+8x+5

    yeah. check out chapters 1-4: linear, quadratic, polynomial and logarithmic functions. you will be able to tell the movements and shifts and of the functions in no time, how many turning points (global/local maximum and minimums), and their values. I use wolfram alpha instead of TI calculators for best FIT models, but not on the problem you posted. I uploaded the whole textbook by Larson et al. to share.

    yeah. but you can check out finedrafts.com/files and just look for Pre-Cal by Larson et al. the rest are physics and biology textbooks that I used.
