Question

solve with a quadratic equation. the product of two consecutive odd integers is 2, 115. Find the integers.

Answer 1

x + x+1= 2,115, solve for x ^_^

consecutive integers are :

x, x+1, x+2, x+3 etc

Answer 2

wait, is it x? or x+1 as a starting point lol @_@

Answer 3

ax^2 + bx + c = 2

a(x+2)^2 + b(x+2) + c = 115

Answer 4

what do the 2 and 115 mean? that (x)(x+2) = 2 and 115?

Answer 5

im not sure, it just puts 2, 115 :-/

Answer 6

or the (2+n)(2+(n+2)) = 115?

Answer 7

a(2^2) + b(2) + c = 115 is what I think it means

Answer 8

when x=2; y=115

Answer 9

just cant seem to make sense of the question.. :)

Answer 10

ah, well, maybe I'll just wait until monday and ask my teacher about it :P thanks for trying to help tho!

Answer 11

youre welcome :) wish I coulda helped out more tho ;)

Answer 12

i guess it must be product of two odd integers is 115

Answer 13

just for kicks, let me try this...

(2+n)(2+(n+2)) = 115
(2+n)(4+n) = 115
n^2 +6n +8 = 115

n^2 +6n -107 = 0

n= -6/2 +- sqrt(36 + 428)/2

n = -3 +- sqrt(464)/2 ; but that doesnt pruduce 2 consecutive odd integers for me...

Answer 14

n(n+2) = 115
n^2 +2n = 115
n^2 +2n -115 = 0

n= -4/2 +- sqrt(4 + 230)/2

n = -2 +- sqrt(234)/2...which isnt 2/2 so that busts as well.....

Answer 15

yea i tried ...same result

Answer 16

there is something missing

Answer 17

2,115 seems like a pair of coordinates.... but that doesnt make sense to me either...

Answer 18

does f(2) = 115? and f(-2)=115? but then where doe we get the two consecutive number to play into it?

Answer 19

if anything the 2 roots would multiply to get a number; but it aint 115..and it aint 2 that I can see

Answer 20

did u try......product=2115???

Answer 21

no, but then again I didnt try product = 47 either :)

Answer 22

y 47?

Answer 23

lol..... why 2115?

Answer 24

like some ppl write 2115 as 2,115 :)

Answer 25

i wasnt making a fun of u :)

Answer 26

ahhhh!! damn yankees lol

Answer 27

(n-47)(n+45)=0

Answer 28

awwwwwww

Answer 29

wrong :(

Answer 30

(n)(n+2) = 2115

n^2 +2n -2115 = 0

n = -4/2 +- sqrt(4 + 8460)/2

n= -2 +- sqrt(8464)/2....

Answer 31

hmmmm

Answer 32

n = -2 +- 92/2

Answer 33

its either 2 negs or 2 pos to get 2115 right?

Answer 34

n^2+2n-2115=0
(n+47)(n-45)=0

Answer 35

n=47
47+2=49

Answer 36

yes right

Answer 37

47(49)=2303

Answer 38

yes :(

Answer 39

its just a broken question ;)

Answer 40

:D

Answer 41

but where is the real prob??when the factorization is correct

Answer 42

oh 45 and 47 is the right choice

Answer 43

likewise -45 and -47

Answer 44

so product =2115 is the actual problem :)

Answer 45

45 and 47 produce 2115; yes :)

Answer 46

m so bad in calculations :P

Answer 47

so it was just a wrong (,) there :P

Answer 48

you did good :)

Answer 49

so starlit u dont need to wait for monday...the solution is there for u

Answer 50

nooooo, factoriztion was correct,but.........
