okay. first you need to being all the terms to one side. So bring in the 16+8x - 4x^3 to the left hand side of the equation and post what you got here.

x^4+2x^3-8x-16=0
anonymous
  • anonymous
okay great. What is common in the first two terms x^4 and 2x^3?

x^2
anonymous
  • anonymous
are you sure about that?
anonymous
  • anonymous
no its x^3
anonymous
  • anonymous
okay. so factor out the x^3 in the first two terms and post what you got.
anonymous
  • anonymous
x^3(x+2)
anonymous
  • anonymous
good! next lets move on to -8x -16. what is common in those two terms?
anonymous
  • anonymous
4?
anonymous
  • anonymous
are you sure?
anonymous
  • anonymous
what is 8 times 2?
anonymous
  • anonymous
16
anonymous
  • anonymous
so its 8..
anonymous
  • anonymous
okay what is -8 times 2?
anonymous
  • anonymous
-16
anonymous
  • anonymous
so what can you factor out?
anonymous
  • anonymous
im confused..
anonymous
  • anonymous
-8x-16. what can you factor out here?
anonymous
  • anonymous
-8(x-2)
anonymous
  • anonymous
correct
anonymous
  • anonymous
no -8(x+2)
anonymous
  • anonymous
yes, that is correct.
anonymous
  • anonymous
-8(x+2) is correct
anonymous
  • anonymous
so the whole equation is what X^3(x+2)-8(x+2) right?
anonymous
  • anonymous
yea
anonymous
  • anonymous
im sorry, it is x^3(x+2)-8(x+2)=0
anonymous
  • anonymous
so what can you factor out here?
anonymous
  • anonymous
(x^3-8)(x+2)=0 x=-2,2 is the answer

thinker, I was in the middle of explaining the whole problem from beginning to end so that car could do it on his own without me thinking for him and doing his calculations for him.
anonymous
  • anonymous
i wanted to figure it out myself
anonymous
  • anonymous
that is not how he will learn.
anonymous
  • anonymous

ur welcome ! :)
anonymous
  • anonymous
by the way im a girl lol
anonymous
  • anonymous
sorry, lol
anonymous
  • anonymous
alright car, good luck .Look for patterns when you are asked to solve or simplify equations.
anonymous
  • anonymous
ok!
anonymous
  • anonymous
what if the problem is x/x^2-4 + 1/x+2 =3..do i solve it the same by bringing the 3 to the other side?
