Plz fast. it's pre calculus. this is the only day i get to spend time with my baby sister. fast. will mark brainliest. which of the following is a root of the polynomial shown below? look at the graph of the function and find the solutions. f(x)=x^3+2x^2-x-2 a.1 b.0 c.3 d.2 which of the following represents the set of possible rational roots for the polynomial shown below? this question is a review from algebra 2. remember that possible rational roots take the form of p/q. where p is a factor of the constant and q is a factor of the leading coefficient. 2x^3+5x^2-8x-20=0

Step-by-step explanation:

Given is the polynomials as

1)

The graph of this function has x intercepts as

-2, -1 and 0

Since f(x) =0 has solutions equivalent to x intercepts we see that the roots are

-2,-1 and 0

2) Given is a polynomial as

Using rational roots theorem we find that

the roots possible are ±1.±2,±4,±5,±10,±20,±1/2,±5/2

Using remainder theorem we see that

f(2) =f(-2)=0

By using division, we find that the other factor is 2x+5

Hence roots are 2,-2, -2.5

dude thats to long figure it

step-by-step explanation:

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
