\[5^3+3(5^2)-6=194\]
anonymous
  • anonymous
got it?
anonymous
  • anonymous
no i don't saljudieh,

we have x=5, it means we are dividing by x-5 to get the value of P(5) write the coefficients of P(x)= x^3+3x^2-6 coefficients are 1 3 -6
ash2326
  • ash2326
got till here?
anonymous
  • anonymous
where did you get the 1 coefficient from? the x right?
ash2326
  • ash2326
yeah x^3 = 1 3x^2= 3 -6 as it is
anonymous
  • anonymous
okay, so where do you get the numbers that go under neath,
ash2326
  • ash2326
now we are using synthetic division first step write this way _______________ 5 | 1 3 -6
anonymous
  • anonymous
wait ash, i messed up the problem was Use synthetic substitution to evaluate P(x) = x3 + 3x2 - 6 for x = -1. P(-1) =
ash2326
  • ash2326
now we have _______________ 5 | 1 3 -6 bring the first term 1 as it is down , _______________ 5 | 1 3 -6 1 next multiply , the term brought down by 5 and ____________________________ 5 | 1 3 -6 5(5*1) 1
anonymous
  • anonymous
:/ im sorry, so it would be _______________ -1 | 1 3 -6
ash2326
  • ash2326
no we have to evaluate at x=5 so it's _______________ 5 | 1 3 -6
anonymous
  • anonymous
i know but i typo'd the problem its P(-1) :/
anonymous
  • anonymous
so it would be 3 5 which is 15 so then would i divide 15 by -6 and get the answer?
anonymous

hey arricuhh u wanna learn? watch thishttp: http://www.youtube.com/watch?v=-aTMzg4syy8
anonymous
  • anonymous
well thanks.
anonymous
  • anonymous
did it help?
anonymous
  • anonymous
so is the answer -8 ?
anonymous
  • anonymous
nope, it did help. but i still got the wrong answer.
anonymous
  • anonymous
wait is it -5?

|dw:1328504343410:dw| ok look at this:
anonymous
  • anonymous
\[x^3+3x^2(no x so you PUT ZERO) -6\]you were messing a term of zero instead of the x term.. coz you had
anonymous
  • anonymous
saljudieh07 i messed up tho and the question is Use synthetic substitution to evaluate P(x) = x3 + 3x2 - 6 for x = -1. P(-1) = i accidently put 5. im going to try it again because i forgot the 0.
anonymous
  • anonymous
yeh whe you have the zero it will work
anonymous
  • anonymous
gdluck i g2g for now byee
anonymous

okay thank you! (:
