Question

i need to get t:
H=16t^2+14t

Answer 1

Solve for t in terms of h? Or what?

Answer 2

im not sure

Answer 3

i just need h to be zero but idk how to figure out what t is

Answer 4

Ok well if h=0 we can easily work with that.

Answer 5

if h = 0, then 16t^2 +14 t = 0

Answer 6

Look for a common factor of both terms and factor it out.

Answer 7

ok so i guess i dont know how to get rid of the squared

Answer 8

Ok so 2t would be a factor correct?

Answer 9

yeah

Answer 10

So if 2t is a factor then what would you be left with? So 2t times what is the same as \[16t^2+14t\] ?

Answer 11

8t+7

Answer 12

Yes. So you get \[2t(8t+7)=0\] All you need to do now is solve for t :)

Answer 13

thank you :)

Answer 14

No problem.
