Answer:
4x^2 - 1 = 0
Step-by-step explanation:
x = 1/2, x = -1/2
2x = 1, 2x = - 1
2x - 1 = 0, 2x + 1 = 0
( 2x - 1 )( 2x + 1 ) = 0
4x^2 - 1 = 0

Answer: 5 seconds
<u>Step-by-step explanation:</u>
Maximum height is the y-value of the vertex. The number of seconds at maximum height is the x-value (aka axis of symmetry).
h(x) = -2x² + 20x + 48
a=-2 b=20 c=48
Axis of symmetry: x =

= 5
