Question 555680: Help, please? I've been having trouble with these problems for my homework.
Use factoring to find the zeros of the quadratic function.
1) G(x)=x^2+5x
2) F(x)=x^2-x-6
3) f(x)=x^2+2x-120
An object is propelled vertically upward from the top of a 256-foot building. The quadratic function s(t)=-16t^2+176t+256 models the ball's height above the ground, s(t), in feet, t seconds after it was thrown. How many seconds does it take until the object finally hits the ground?
Any help really, I'd be tremendously grateful.
