How are the polynomial fractions subtracted?
Since the denominators of the fractions are same,
By, factorization of the polynomial fractions,
What are polynomial fractions?
- Polynomial fraction is the result of dividing one polynomial by another.
- By factorizing and reducing them to the lowest terms, a polynomial fraction can be made simpler when a polynomial appears in either the numerator or the denominator.
- A fraction in which either the numerator or the denominator are polynomials is the same as a rational expression.
- Factoring the polynomial entirely within the numerator and the denominator is necessary in order to factor it completely.

Answer:
57
Step-by-step explanation:
There are 60 data altogether.
Therefore, n=60
50th percentile = 50%*(n+1)
=50/100*(60+1)
=30.5
This implies that the 50th percentile is between the 30th and 31st data
30th data= 57 ; 31st data = 57
since they are the same figure, 50th percentage = 57
Answer:
yes

Answer:
6
Step-by-step explanation:
Use the slope formula:
Picking x = 2 and x = 4 as my two points (since the interval is 2 ≤ x ≤ 4), we get:
So, the BEST estimate of the average rate of change for the function given in the table is 6.
I assume the question asks to expand the expression to individual terms.
There are different ways to approach this, all based on FOIL or similar methods.
I prefer to split it into two parts, as follows:
(x+y+2)(y+1)
=x(y+1)+(y+2)(y+1)
=xy+x+y^2+3y+2
