The sum of the two fractional number, which consist in the variable <em>x</em> is in the polynomial function,
Fraction number is the number which is a part of a whole number. It is written with a numerator and denominator.
Fraction number are written as,
Here (a) is the numerator and (b) is the denominator.
To find the sum of two fraction numbers, cross multiply both the numbers or find the least common factor as denominator.
The first fraction number given in the problem is,
The second fraction number given in the problem is,
Let the sum of these number is f(x). Thus,
Solve it further as,
Thus, the sum of the two fractional number is,

Answer: 1) D 2) B
<u>Step-by-step explanation:</u>
1) The denominator cannot equal zero, Factor the denominator to find the zeros. n³ - 4n² + 3n = 0
n(n - 3)(n - 1) = 0
n=0 n-3=0 n-1=0
n=0 n=3 n=1
2) In order to be a rational expression, it must be in the form where both a and b are integers.
Since is irrational and not an integer, then the expressions containing an irrational term <em>after simplified</em> cannot result in an integer.
Therefore, options <em>(i)</em> and <em>(iv)</em> are not rational expressions.
Option <em>(iii)</em> contains b as an exponent. Since there is no information about b, it could be a fraction, which means it could be an irrational number.
