To simplify this, we need to do PEMDAS (parenthesis then exponents, then multiplication and division, then addition and subtraction). Here, we can't combine any like terms in the parenthesis. Since there's no exponents, that means that the next step is to do multiplication. This gives us:
3 - 15y - 21 + 2y - 6
Now we can combine like terms.
(-15y + 2y) + (3 - 21 - 6)
-13y - 24
Answer:
the factors of f(x)=x^3+8x^2+5x-50 are (x-2)(x+5)(x+5)
Step-by-step explanation:
We need to factorise the function 
If a number is a factor of this function than it must be completely divisible by last co-efficient. Our last co-efficient is -50
Checking few numbers:

So, f(2)=0 which means x-2 is a factor of the given function. Now we will perform long division of
by (x-2) to find other factors
The long division is shown in figure attached.
After long division we get: 
The equation
can be further simplified as: (x+5)(x+5) or (x+5)^2
So, the factors of f(x)=x^3+8x^2+5x-50 are (x-2)(x+5)(x+5)

Step-by-step explanation:
12000 abitanti all'inizio del 2007
nati: 1.7% × 12000 = 204
morti: 2% × 12000 = 240
popolazione all'inizio del 2008: 12000 + 204 - 240 = 11964
