1. Solve 3x2 + 18x + 15 = 0 by completing the square.

3(x + 3)2 = 6; x = −3 + , x = −3 −
3(x + 9)2 = 12; x = −11, x = −7
3(x + 3)2 = 12; x = −5, x = −1
3(x + 9)2 = 228; x = −9 + , x = −9 −

2. Two sets of quadratic expressions are shown below in various forms:

Line 1: x2 − x − 6 (x + 2)(x − 3) (x + 0.5)2 − 6.25
Line 2: x2 − x − 2 (x + 1)(x − 2) (x − 0.5)2 − 2.25

Which line contains three equivalent expressions?

Line 1 only
Line 2 only
Both Line 1 and Line 2
Neither Line 1 nor Line 2
