Answer:

Step-by-step explanation:
Given that:
Difference of two trinomials is 
One of the two trinomials is 
To find:
The other trinomial = ?
Four options are:

Solution:
Let the two trinomials be A and B.
Given A - B = 
B = 
We have to find the other trinomial A.
A - B = 
A - (
) = 
A =
+ (
)
A = 
So, the correct answer is
.
Answer: same

Answer: C
Step-by-step explanation:
1+2e^x+1=9
2e^x+1=9-1
e^x+1= 8/2
e^x+1 = 4
Here we can applicate the Ln:
ln e^x+1 = ln 4
Applicating the log property for exponent:
(x+1).ln e = ln 4
Ln e = 1, so:
x+1 = ln 4
x = ln 4-1
