Answer:
(x+1)(x-1)(x+3)(x-3)
Step-by-step explanation:
x4-10x^2+9
Group expression so that the coefficients of the x^2 terms add up to +9.
= x^4 -9x^2 - x^2+9
match coefficients in both groups
= x^4 -9x^2 - (x^2-9)
factor each group
= x^2 (x^2-9) - 1(x^2-9)
now factor out the common factor (x^2-9)
= (x^2-1)(x^2-9)
Finally, factor each quadratic factor
= (x+1)(x-1)(x+3)(x-3)
Answer:
$72,100
Step-by-step explanation:
To calculate the total principal+interest payment, you can use the formula to find the future value:
FV=PV(1+i)^n
FV= Future value
PV= Present value= $58,200
i= Interest rate= 7.40%
n= Number of periods of time= 3 years
Now, you can replace the values on the formula:
FV=58,200*(1+0.0740)^3
FV=58,200*(1.0740)^3
FV=72,100
According to this, the answer is that the total principal + interest payment will be $72,100.

Answer:
Step-by-step explanation:
1. 6(a +2b +3c)
2. (6 x 1a) + (6 x 2b) + (6 x 3c)
*Note that I put a 1 in front of the a. I did this because a means there is 1a so by putting the 1 there, it makes it easier to see that 6 x 1= 6, therefore we now have 6a.
3. Answer:
(6a) + (12b) + (18c)
* If you ever have an equation like this that has two of the same letters such as if 12b was 12a, then you could combine those since they are like terms. But since we have three different letters, this is the most simplified answer. Hope this helps!!(: If you have any questions just let me know!
