Question

An object is thrown upward from the top of a 192-foot building with an initial velocity of 16 feet per second. The height of the object after the t seconds is given by -16t^2+16+192. Factor this polynomial.

Answer 1

the website wants the answer written a certain way........... it wants it to look like this -16(t- )(t+ )

Answer 2

check that
is it
\[\Large -16t^2+16t+192 \] ???

Answer 3

-16t^2+16+192. Factor this polynomial.

Answer 4

i assume it should be what i wrote above because this is the only way you will get required format of answer i think you are missing t with 16 .
take -16 common
-16(t^2-t-12)
can be written as
-16(t^2-4t+3t-12)
-16( t(t-4)+3(t-4))
-16((t-4)(t+3))

Answer 5

it's says sorry that is not correct..... this is what it has underneath................. First factor out the greatest common factor ( if there is one other 1 or -1) then factor the remaining trinomial

Answer 6

-16(t^2-t-13)

Answer 7

saifoo that is not the way they want to answer........... they want the answer to -16(t- )(t+ )

Answer 8

it should be
if they want that way then you must know than there must be term with t which you are missing because
(t+a)(t-b)=t^2-bt+at-ab

Answer 9

How I wrote the question on here is the exact way that its it on the website

Answer 10

lets try what you wrote
can be written as
-16(t^2-13)
then use
\[\Large a^2-b^2=(a+b)(a-b)\]
\[\Large -16(t^2- \sqrt{13)}^2=-16(t+\sqrt{13})(t-\sqrt{13})\]

Answer 11

no that is not the right answer either....... I get the same sorry that is not the correct answer

Answer 12

Maby try multiplying to get rid of the "-" but i doubt thats it, and only do that if you have unlimited answers for your question

Answer 13

post a screenie of the solution field(s)

Answer 14

I have three chances to get the right answer then I have to go to another problem like it.. This is the 7 problem that I have worked.

Answer 15

I can't do a screenie

Answer 16

it says beneath that its a 'trinomial' means it must contain 3 different terms---> -16t^2+16t+192
-16t^2+16+192 is a binomial, not trinomial....

Answer 17

it's a polyomial

Answer 18

An object is thrown upward from the top of a 192-foot building with an initial velocity of 16 feet per second. The height of the object after the t seconds is given by -16t^2+16+192. Factor this polynomial.

Answer 19

but is it explicitly mentioned beneath "factor the remaining trinomial" ?
because what remians is binomial, not trinomial

Answer 20

I have been on the problem for an hour and half now

Answer 21

I have no ideal what you are talking about hartnn.......... I reposted the questions

Answer 22

they want the answer to be in form of this -16(t- )(t+ )
