1/x+1; where x ≠ -1, -5
1/x-5; where x ≠ 5
x-5
Answer:
The correct option is 2.
Step-by-step explanation:
The given rational expression is
Factorize the denominator.
The middle term can be written as 5x+x.
Cancel out the common factors.
The simplified form of the given expression is . The factors of the denominator are (x+5) and (x+1), it means at x=-5 and x=-1, the value of denominator is zero.
The given expression is not defined for x=-1 and x=-5.
Therefore the correct option is 2.
A. 2X+5X+7-3
B. 4X-2Y=10X
C. 2P+12+2P-8
