Best ResponseYou've already chosen the best response.1Part A: Describe the solution(s) to the equation by just determining the radicand. Show your work. (3 points) .....9x²  36x + 36 = 0 .....9(x²  4x + 4) = 0 .....9(x2)(x2) = 0 .....Radicand = Discriminant = 36²  4(9)(36) = 0 .....⇒ there is 1 real zero of miltiplicity 2 (in other words, .....there is 1 real zero that repeats itself) .....That zero is x=2. Part B: Solve 2x^2  9x + 7 = 0 using an appropriate method. Show the steps of your work and explain why you chose the method used.(4 points) .....2x²9x+7 = 0..........// Use factoring. Factors of 7 are 1 and 7 .....(2x7)(x1) = 0 ..........2x7 = 0............(x1)=0 ..........2x = 7................x=1 ..........x = 7/2 .....Your solutions are x=1 and x=7/2 Part C: Solve 3x^2  12x + 2 = 0 by using a method different from the one you used in Part B. Show the steps of your work. (3 points) .....3x²  12x + 2 = 0 ............(12)±√((12)²4(3)(2)) .....x = ....// Solve by Quadratic formula .....................2(3) ............12±√(14424) .....x =  .....................6 ............12±√120 .....x =  .....................6 ............12±2√30 .....x =  .....................6 .....x = 2±(1/3)√30
