1. The equation \(y = -16t^2 + 28t + 144\)describes the height (in feet) of a ball tossed up in the air at 28 feet per second from a height of 144 feet from the ground. In how many seconds will the ball hit the ground?

2.The roots of \(x^2 + 5x + 3 = 0\)

are p and q and the roots of

\(x^2 + bx + c = 0\)

are p^2 and q^2 Find b+c
