Answer:
There are two rational roots for f(x)
Step-by-step explanation:
We are given a function
To find the number of rational roots for f(x).
Let us use remainder theorem that when
f(a) =0, (x-a) is a factor of f(x) or x=a is one solution.
Substitute 1 for x
f(1) = 1-2-5+6=0
Hence x=1 is one solution.
Let us try x=-1
f(-1) = 1-2-5+6 =0
So x =-1 is also a solution and x+1 is a factor
We can write f(x) by trial and error as
We find that factor gives two irrational solutions as
±√3.
Hence number of rational roots are 2.
Answer:
Option B.
Polygon JKLP maps to polygon MNOP through a rotation.
Step-by-step explanation:
The picture of the question in the attached figure
we know that
If two figures are congruent, then its corresponding sides and its corresponding angles are congruent
In this problem
JK≅MN
KL≅NO
LP≅OP
JP≅MP
and
∠OPM≅∠LPJ
∠NOP≅∠KLP
∠ONM≅∠LKJ
∠NMP≅∠KJP
so
Polygon JKLP maps to polygon MNOP through a rotation clockwise around point P an angle equal to ∠JPM
