help !!!!
use the p/q method where \[\large\rm \frac{ p }{ q}= \frac{\pm ~~all~factors ~of~constant~term}{\pm~~all~factors ~of ~leading ~coefficient }\]
the leading coefficient is 8 and 10 right?
there should be only one leading coefficient coefficient of the highest degree variable
10?
what's the highest degree (exponent ) ??
8 sorry
yes correct write all factors of 8 and factors of constant term
3x^4+10x^3-11x^2-10x / 8?
no. what's the constant term in that function ?
x?
that's the variable what would be the leading coefficient and constant term? here is an example \[4x^2+3x+9\] 4 is leading coefficient(coefficient of highest degree variable ) cosntant term is 9( number without any variable )
constant*
8 is the constant
correct and leading coefficient is ?
11x^2
what's the highest exponent in that function ? if u look at my example it was 2 so that's how leading coefficient was 4 \[\large \rm Ax^5+Bx^3+C\]in this example highest exponent is 5 leading coefficient is `A`
3x^4
that's the term where just 3 is leading coefficient and now what are the factors of 8 and 3 ?
@Nnesha is correct. Here is a slightly different way to look at it
you divide 8/3?
question (not to interrupt) does not ask for the "possible" rational zeros, it asks for the zeros
no divide factors of 8 by the factors of of 3 i know they r looking for real zero so she can just graph it
it is not necessary to list all possible rational zeros of this, in fact it is mostly a waste of time you want to find the actual zeros, not the possible rational ones, as there are many
unless you want to make a to see which ones to check
"make a list"
@satellite73 the idea is to generate all the possible rational roots then you check each possible root in f(x). If f(x) = 0, then you have a true actual root it might be easier just to go through your answer choices
i would certainly say so!!
huh?
you have choices right? check which ones work
how do i check?
plug in the number
see if you get zero
?
|dw:1449286024847:dw| zeros (or x-intercept ) point when graph intersect the x-axis when y=0 so you can substitute given points for x if you get 0 as final answer then that number would be the zero
