divide your polynomial by the options. if the remainder is 0, you have found a factor
anonymous
  • anonymous
you can also use the remainder theorem f(5) will output the remainder that you would get by dividing your polynomial by (t-5)
anonymous
  • anonymous
so the answer is t-5?

when you use the reaminder theorem, and you plug it into the equation, I get 450 not zero.
anonymous
  • anonymous
or I mean how would you do it as a remainder theorem problem
anonymous
  • anonymous
so if f(5) is not equal to 0, then t-5 is not a factor
anonymous
  • anonymous
try the others
anonymous
  • anonymous
ooh and the right one is the one thats going to be zero?
anonymous
  • anonymous
yes
anonymous
  • anonymous
okay thanks a lot!
anonymous
  • anonymous
for (t+5) to be a factor, f(-5) would have to be 0
anonymous
  • anonymous
thank you!
