Answer:
= 
Step-by-step explanation:
In this case in order to simplify we need to know what the "power rule of exponents" is. Simply speaking this rule states that when you raise a power to a power you multiply the exponents. So in our case we ill get the following
=
In order to get 42 we used the power rule which I mentioned earlier.
When you see an equation with parenthesis around it, you can use this:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
Otherwise known as PEMDAS.
We can see that in the equation, there are parenthesis, so we can open those. We open parenthesis by taking the number right next to the parenthesis (or outside the parenthesis) and we multiply that number by everything inside. So this is what it would look like:
-2x^2 - 10x + 8
See how the signs changed? This rule only applies when you multiply something, but here is how I think of it:
+ and + always equals +.
- and - always equals +.
- and + always equals -.
+ and - always equals -.
So that's it! Just to be clear, the answer is:
-2x^2 - 10x + 8
Hope I helped, sorry if I'm wrong!

Answer:
$3600
Step-by-step explanation:
In each case, the repair cost exceeded the deductible, so your out-of-pocket cost for 2 repairs is ...
2 × $1050 = $2100
In addition, you had to pay the premium of $750 per 6-month period, or $1500 per year, so your total was ...
$2100 +1500 = $3600 . . . out-of-pocket total
