Question

A trinomial has:
Select one:
1 term, like x
2 terms, like x + 25
3 terms, like x^2 + 5x + 25
4 terms, like x^3 + x^2 + 5x + 25

If the last sign in a trinomial is positive, the signs of your factors are:
Select one:
Always both positive
Always both negative
Either both positive or both negative
One positive and one negative

If the last sign in a trinomial is positive and the first sign is negative, the signs of your factors are:
Select one:
Always both positive
Always both negative
Either both positive or both negative
One positive and one negative

Answer 1

If the last sign in a trinomial is negative, the signs of your factors are:
Select one:
Always both positive
Always both negative
Either both positive or both negative
One positive and one negative

Plug in the signs you would use to factor the trinomial:

x^2 – 2x – 15
Select one:
( + )( + )
( - )( - )
( + )( - )
None of the above

Answer 2

which do you think it is?

Answer 3

for?

Answer 4

there are 5 different question I probably should have numbered them

Answer 5

for the first one I think its 2 terms like x -25 for the first one
second questions I think its positive or negative

Answer 6

you know, reading the question again makes me wonder, are you suppose to pick one form the 4 options and answer the questions or for all 4?

Answer 7

A. 1 term, like x
B. 2 terms, like x + 25
C. 3 terms, like x^2 + 5x + 25
D. 4 terms, like x^3 + x^2 + 5x + 25

2. If the last sign in a trinomial is positive, the signs of your factors are:
Select one:
A. Always both positive
B. Always both negative
C. Either both positive or both negative
D. One positive and one negative

3. If the last sign in a trinomial is positive and the first sign is negative, the signs of your factors are:
Select one:
A. Always both positive
B. Always both negative
C. Either both positive or both negative
D. One positive and one negative

4. If the last sign in a trinomial is negative, the signs of your factors are:

B. Always both negative
C. Either both positive or both negative

Answer 8

oh haha okok sorry! thanks, you are being really patient

Answer 9

Yeah no problem! :)

Answer 10

so for question 1 you got B or C?

Answer 11

B?

Answer 12

No wait thats wrong! Its actually 3 terms

Answer 13

So C and I got C for question number 2 as well

Answer 14

yep C for 1 and 2 it's C also, good work ^_^
now for question 3..

Answer 15

I am stuck on that one..

Answer 16

back, sorry. soo..

Answer 17

its ok

Answer 18

So yeah i don't know question 3

Answer 19

so if the trinomial looked like this:
x^2 - 4x + 4
what would these signs have to be to get the x^2 - 4x + 4
(x ? 2)(x ? 2)

Answer 20

always both negative?

Answer 21

thats right :D

Answer 22

yep ^_^ good work.
now question 4?

Answer 23

3. If the last sign of the trinomial is positive and the first sign is negative, then the signs of the binomials are both negative

4. If the last sign of the trinomial is negative, then one binomial will have a positive sign and one will have a negative sign

Answer 24

4. is d

Answer 25

right again

Answer 26

ok

Answer 27

questoin 5..

Answer 28

hm? well the numbers are both negatives

Answer 29

is 5 c?

Answer 30

right again ^_^

Answer 31

I have one more! :O I got stuck on

Answer 32

Plug in the signs you would use to factor the trinomial:

x2 + 9x + 14
Select one:
( + )( + )
( - )( - )
( + )( - )
None of the above

Answer 33

no problem! put it up

Answer 34

it says of the last sign of the trinomial is positive that means the factors are either both positive or both negative. So they gave me an option of them being two negative and two positives and I can only chose one!

Answer 35

I'm thinking its (D) None of the above.

Answer 36

haha, this sounds like a trick question!

Answer 37

yeah

Answer 38

here is what we have learned:
( - )( + ) gives last term -
( + )( + ) gives last term +
( - )( - ) gives last term +
so it's a trick question i think

Answer 39

So the answer is none of the above?

Answer 40

mm.... I wouldn't say none of the above, is there a choice for 'two of the above'? becuae we know it can happen in two ways

Answer 41

no lol

Answer 42

if it were me, i'd pick the one that says:
(+)(+)

Answer 43

ok! I'll try it out. Thank you :D

Answer 44

ur welcome
