1. Solve by using inverse operations. Find exact answers and then round any irrational numbers to two decimal places. a. (x-4)249 = b. -3(x+5)2 + 60 = 0 2. Solve by factoring. a. 16x2 - 9 = 0 b. x2 = 300 - 20x 3. Solve using an appropriate algebraic method. Express your answers exactly. a. (7d 10)2-3 = 17 b. 25r84 = 0 c. 9v245v = 0 d. 9 = 25(d-4)2 e. 4x24x-3=0 f. (3x-5)(x-5)= 32 4. Check your answers to Exercises 3b) and 3f) using a formal LS, RS check. 5. Identify if the following are quadratic equations or not. a. 2x2-7=-3 b. x(3x2-x-2) = 0 c. 8x+6=4 d. (x - 11)(x+11) = 1 -4x e. x = 9 6. Find a quadratic equation (in the form ax + bx + c = 0, where a, b, and c are integers) with roots: 2 a. 3 and -5 b. -328
