Answer:
There are two rational roots for f(x)
Explanation:
We are given a function
f(x) = x^6-2x^4-5x^2+6f(x)=x6−2x4−5x2+6
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
f(x) = (x-1)(x+1)(x^2-3)f(x)=(x−1)(x+1)(x2−3)
We find that f(x) (x^2-3)f(x)(x2−3) factor gives two irrational solutions as
±√3.
Hence number of rational roots are 2.

Normal human body cells are diploid and the basic chromosomes number of human cell is (n) 23. Thus, a normal human cell has (2n) 46 chromosomes out of which 44 are autosomes and 2 are gender chromosomes XY.

What are chromosomes?</h3>
Chromosomes are threadlike structure of nucleic acids and protein present in the nucleus of living cells, carry genetic information in the form of genes.
The "X" or "Y" gene which determines whether new born will be a boy or a girl is an example of a chromosome. the below diagram representing the chromosome.
