Answer:
Step-by-step explanation:
To find the real zeros you must match the function to zero and factor the expression.
We have a polynomial of degree 3.
We try to group the terms to perform the factorization
Now we take (x + 4) as a common factor
If we have an expression of the form we know that this expression is equivalent to:
In this case
So:
Finally:
The solutions are:
Answer:
$389.35
Step-by-step explanation:
A certain computer costs $599.00 at Best Buy. On Black Friday, it is on sale for 35% off.
