How do you divide polynomials using long division

levacccp [35]

This is a simple example:-
x + 9
------------------------------
x - 1 ) x^2 + 8x - 9
x^2 -   x subtract
------------
   9x - 9
   9x - 9
----------
..........

First divide x into x^2 to give x which goes above
Then multiply x - 1 by x to give x^2 - x

Subtract this fro x^2 + 8x gives 9x
Bring down the - 9 then divide x into 9x
and finally multiply x - 1 by 9 to give 9x - 9
Finally subtract and you sre done. There is no remainder as x - 1 is a factor of x^2 + 8x - 9.

The polynomial must be in descending powers of x . If one is missing you insert it with a coefficient of zero before you start the division.

for example if you have x^3 - 3x + 12 you write it as

x^2 + 0x^2 - 3x + 12

Answer:

69 and 30

Step-by-step explanation:

Using the formula with d = 96

$T_{max}$ = $\frac{2(96)}{3}$ + 5 = $\frac{192}{3}$ + 5 = 64 + 5 = 69 in

$T_{min}$ = $\frac{96}{3}$ - 2 = 32 - 2 = 30 in

Given:
p = 20% = 0.2, sample proportion
n = 5000, sample size.
Confidence level = 95%

The confidence interval is
(p - 1.96k, p + 1.96k)
where
$k=\sqrt{ \frac{p(1-p)}{n} }=\sqrt{ \frac{0.2*0.8}{5000}} =0.00566$

Therefore the 95% confidence interval is
(0.1943, 0.2057) = (19.4%, 20.6%)

Answer: The 95% confidence interval is (19.4%, 20.6%)
