A quadratic equation is shown below:
3x2  16x + 2 = 0
Part A: Describe the solution(s) to the equation by just determining the radicand. Show your work. (3 points)
Part B: Solve 9x2 + 3x  2 = 0 by using an appropriate method. Show the steps of your work, and explain why you chose the method used. (4 points)
Part C: Solve 3x2  10x + 2 = 0 by using a method different from the one you used in Part B. Show the steps of your work. (3 points)

Best ResponseYou've already chosen the best response.0yes...it's not going to be a rational number. sometimes teachers will ask that you simplify what's in the radical, but I wouldn't unless you know you have to.
