Brainliest ! a quadratic equation is show below: 9^2 - 16x + 60 = 0 part a: describe the solution(s) to the equation by just determining the radicand. show your work. part b: solve 4^2 + 8x - 5 = 0 by using an appropriate method. show the steps of your work, and explain why you chose the method used.

If what you are looking for in part A is the number of solutions for the following 
 9x² - 16x + 60 = 0 then the determinant defined by 
would be:
and this produces a negative value under the radical. Therefore, there would be no real solutions to this quadradic

For Part B:  the best solution strategy would be factoring as such:
4x² + 8x - 5 = (2x - 1)(2x + 5)  and setting each binomial factor equal to "0" and solving, you find your solutions to be  x = 1/2  and x = -5/2
