The rational root theorem tells you all roots are of the form
±(factor of 2)/(factor of 3)
We know one of the roots is -1 and all roots are negative, so the remaining roots must be of the form
-(factor of 2)/(factor of 3)
which is to say, two of
-1/3, -2/3, -1, -2
Since the roots are distinct, they must be -2 and -1/3. Then the factorization of the given polynomial is
(x +1)(x +2)(3x +1)
which multiplies out to be
3x³ +10x² +9x +2

a = 10
b = 9

$947.50 - $189.50 = ? Am I not smart or what?

$947.50
 - $189.50
_________
$758.00

So, to do this first we start at the far right and go to the left.

$947.50 - $189.50_________
$ .00
0-0= 0
5-5= 0

You then bring down the decimal.

$947.50 - $189.50_________
$ 8 .00
Because you cannot subtract 9 from 7, you borrow one from the number to the left of it and 7 turns into a 17 as 4 turns into a 3. So then, 17-9=8.
17
$93-7-.50 -7- = This means the 7 has been canceled out and turned - $189.50 into the 17 above _________ 8 .00
This happens again with subtracting 3 from 8 in which you take one from the number beside which happens to be 9 and make it 8.

17
$8-3--7-.50 -7- and -3- = This means the 7 has been canceled out and turned into the 17 above
- $189.50 _________ $ 58 .00
So then, 13-8=5. Finally 8-1= 7

$947.50
- $189.50
_________
$758.00
