Method 1:
The recursive formula states that every next term is three times the previous one, plus two.
So, we have:
Method 2:
You can write the expression for 
, and use the recursive formula until you get to the starting point:
Now use the fact that 
to get the conclusion
Least common denom
look at denoms (bottom)
m^4 and 2
LCD is 2m^4
tada
18/(2m^4) and (m^4)/(2m^4)
Answer:
Step-by-step explanation:
1. f(-2) = 6 * 1/3^-2
f(-2) = 6 * 9
f(-2) = 54
2. y = -3 * 4^3
y = -3 x 64
y = -192
3. f(4) = 1/4 * 2^4
f(4) = 1/4 * 16
f(4) = 4
Let me know if I am right!
Okay so you split 9ab + 12ax - 6b - 8x
<span> into two 2-term polynomials </span>
+ 12ax + 9ab and - 6b - 8x
doesn't look that good to me so lest try other one :
9ab + 12ax and - 6b - 8x
looks good for now
<span> </span> Pull out from each binomial separately
9ab + 12ax = 3a • (3b + 4x)
- 6b - 8x = - 2 • (3b + 4x)
<span> </span> Add up to arrive at the desired factorization so now you have
<span> (3a - 2) • (3b + 4x)
