    1. Solve by using the perfect squares method. (2x + 4)2 = 64 (Points : 4) {–2, 6} --> {2, –6} {1, –5} {–1, 5} Question 2. 2. Solve. x2 – 5x – 6 = 0 (Points : 4) {2, 3} {–2, –3} {–1, 6} -->{1, –6} Question 3. 3. What value should be added to the expression to create a perfect square? x2 – 10x (Points : 4) 5 25 100 --> –100 Question 4. 4. Solve. x2 + 8x + 10 = 0 (Points : 4) Question 5. 5. Solve: 6x2 + 12x = 0 (Points : 4) {–6, –2} {0, 2} {0, –2} Question 7. 7. Calculate the discriminant. x2 – 3x + 5 = 0 (Points : 4) 9 7 –7 --> –11
