x + x+1= 2,115, solve for x ^_^ consecutive integers are : x, x+1, x+2, x+3 etc
wait, is it x? or x+1 as a starting point lol @_@
ax^2 + bx + c = 2 a(x+2)^2 + b(x+2) + c = 115
what do the 2 and 115 mean? that (x)(x+2) = 2 and 115?
im not sure, it just puts 2, 115 :-/
or the (2+n)(2+(n+2)) = 115?
a(2^2) + b(2) + c = 115 is what I think it means
when x=2; y=115
just cant seem to make sense of the question.. :)
ah, well, maybe I'll just wait until monday and ask my teacher about it :P thanks for trying to help tho!
youre welcome :) wish I coulda helped out more tho ;)
i guess it must be product of two odd integers is 115
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...
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.....
yea i tried ...same result
there is something missing
2,115 seems like a pair of coordinates.... but that doesnt make sense to me either...
does f(2) = 115? and f(-2)=115? but then where doe we get the two consecutive number to play into it?
if anything the 2 roots would multiply to get a number; but it aint 115..and it aint 2 that I can see
did u try......product=2115???
no, but then again I didnt try product = 47 either :)
lol..... why 2115?
like some ppl write 2115 as 2,115 :)
i wasnt making a fun of u :)
ahhhh!! damn yankees lol
(n)(n+2) = 2115 n^2 +2n -2115 = 0 n = -4/2 +- sqrt(4 + 8460)/2 n= -2 +- sqrt(8464)/2....
n = -2 +- 92/2
its either 2 negs or 2 pos to get 2115 right?
its just a broken question ;)
but where is the real prob??when the factorization is correct
oh 45 and 47 is the right choice
likewise -45 and -47
so product =2115 is the actual problem :)
45 and 47 produce 2115; yes :)
m so bad in calculations :P
so it was just a wrong (,) there :P
you did good :)
so starlit u dont need to wait for monday...the solution is there for u
nooooo, factoriztion was correct,but.........
