Thank you for the opportunity to help you with your question!

h=16t^2+16t+672

direct roots of this problem is not possible so we need to use quadratic formula to solve it

h=[ -b +- sqrt (b^2 - 4ac)] / 2a

in the given problem

a= 16

b=16

c= 672

so put the values in formula

h=[ -16 +- sqrt (16^2 - 4*16*672)] / 2 (16)

h=[ -16 +- sqrt (256 - 43008)] / 32

so h is

h = -1/2 + 6.46 i or h = -1/2 - 6.46 i

H is not 676 kindly check the question may be there is a typing mistake in your question and then let me know i will always be
