Answer:
f(n+1) = 13
Step-by-step explanation:
- We know that f(1) = 15
- So we can substitute this for f(n)-3
- With this:
- f(n+1) = f(1) -3
- f(n+1) = 15-2
- f(n+1) = 13
Answer:

Step-by-step explanation:
2x² + 5x + 3 = (x + 1) (2x + 3)
x² + 2x + 1 = (x + 1) (x + 1)
(x + 1) cancels out because there is one in the denominator and the numerator, leaving you with the answer.
Hope this helps!
Answer:
