Guys please help me solve this its so stressful

Given:-

A parabola attain maximum height at the vertex: formula to find x-coordinate of vertex is,

plug in a=-5 and b=10

so,

Now plug in x=1 to get maximum height,

so, maximum heigh reached by the rocket was 25 yards

Rocket will hit the ground when y=0

So,

quadratic formula is,

plug in a=1, b=-2,and c=-4

So, it takes 3.2 seconds to hit the ground.
