12. While observing a basketball player in action, Pratham wondered if the path traced by the ball during its journey
from the player's hands to the basket is that of a parabola. On reaching home, he traced the path on a graph paper
and was happy to learn that it indeed resembles the shape of a parabola, which is the graph of a quadratic polynomial.
He thought that he can also evaluate the zeroes of this polynomial.
If the zeroes of the quadratic polynomial x² + (a + 1) x + b are 2 and –3, then:
(a) a = –7, b = –1 (b) a = 5, b = –1 (c) a = 2, b = – 6 (d) a = 0, b = – 6
