Do you know how to find the factor of a quadratic expression ?
anonymous
  • anonymous
nope
goformit100
  • goformit100
first try to break 24 in such two halves so that you get 10 as answer

what are two numbers that add to 10 but multiply to 24?
anonymous
  • anonymous
12 and -2
zzr0ck3r
  • zzr0ck3r
that multiplies to -24
anonymous
  • anonymous
yep
zzr0ck3r
  • zzr0ck3r
we want it to multiply to 24 not -24
zzr0ck3r
  • zzr0ck3r
two different numbers?
anonymous
  • anonymous
12 and 2
zzr0ck3r
  • zzr0ck3r
does that add to 10?
zzr0ck3r
  • zzr0ck3r
try other numbers
anonymous
  • anonymous
idk
zzr0ck3r
  • zzr0ck3r
two numbers that multiply to get 24 how else can two numbers multiply to get 24 besides 2*12
anonymous
  • anonymous
1 and 24
zzr0ck3r
  • zzr0ck3r
what else
zzr0ck3r
  • zzr0ck3r
1*2=24 2*12 = 24 ?*? = 24
anonymous
  • anonymous
3 and 8 4 and 6
zzr0ck3r
  • zzr0ck3r
which one of those add to 10?
zzr0ck3r
  • zzr0ck3r
cmon I got to go soon
anonymous
  • anonymous
4 an 6
zzr0ck3r
  • zzr0ck3r
ok, now notice that we have -10 and not 10 as our middle term, but just as 4+6 = 10 and 4*6 = 24, we also have -6+-4 = -10 and -4*-6 = 24 so our numbers are -4,-6
zzr0ck3r
  • zzr0ck3r
and since we dont have a coefficient on the first term, that is the answer
anonymous
  • anonymous
oh okay thank you
zzr0ck3r
  • zzr0ck3r
you should be able to list the combinations of factors to get numbers \[24=1*24=2*12=3*8=4*6=-4*-6=-3*-8=-2*-12=-1*-24=24\]
zzr0ck3r
  • zzr0ck3r
\[=-1*-24=24\]
anonymous
  • anonymous
oh okay
anonymous
  • anonymous
its d right
zzr0ck3r
  • zzr0ck3r
correct
zzr0ck3r
  • zzr0ck3r
you should be able to expand D) and know this for sure, if not...I would really suggest that you go back a few sections/chapter and catch up. Its only going to get harder, and it is 50000000 times harder if you dont understand the material that came before, as we are baring witness too.
