Answer:
26*26*25 = 16,900
Step-by-step explanation:
First, we focus on the first initial, we have 26 letters that could fit in (the whole alphabet).
In the last initial we <em>can't</em> have the same we have in the first one, so we have 25 letters (the whole alphabet minus the letter that we already choose in the first initial
).
We have <em>no restrictions</em> for the middle one, so again we have 26 letters that could fit in.
So, we have 26*26*25 combinations (we multiply them because they happen all at the same time)
There is no need to use factorials, but we can use them if you want to.
Let's notice that 26! = 26*25*24*23*22*...
In our calculation, we only need the two first factors, so we can divide by 24! =24*23*22*21*...
Therefore,
26*26*25 = 26 * 26! /24!

Answer:
116
Step-by-step explanation:
If we assume the quotient is px³+qx²+rx+s
Then the following must hold:
(px³+qx²+rx+s)(x+1) + 14 = x⁴ + ax² - 16
From this we can establish p,q,r and s and then a. Do the multiplication, and then find that:
p=1
p+q=0
q+r=a
r+s=0
s+14=-16
Combine these, and get:
s = -30
r = 30
q = -1
a = 29
Now that we have a, we can do a normal factorization:
(x⁴ + 29x² - 16) = (x³ + 2x² + 33x + 66)·(x-2) + 116
