Let f(x) = ax2 + bx + c, where a, b and c are certain constants and a ≠ 0. It is known that f (5) = −3f (2) and that 3 is a root of f(x) = 0.
1. What is the other root of f(x) = 0? (1) −7 (2) − 4 (3) 2 (4) 6 (5) cannot be determined
2. What is the value of a + b + c? (1) 9 (2) 14 (3) 13 (4) 37 (5) cannot be determined
