-5x2 + 10x + 15 = 0
See how five goes into the 5, 10 and 15. More importantly , you pull out a
negative five to have a nice looking x squared term
-5( x2-10x -3) = 0
Divide by negative 5 and you are left with
x2-10x -3 =0
Now it is time to do this:

For number 5 in Ple drop box
. Find the sum of the first 26 terms of the following sequence:
12, 18, 24 . . .
I can tell this is an arithmetic sequence where 6 is added each time. So the formula to use is this:
We know n is the number of terms AND THE PROBLEM tells us the first 19 terms.
We know a1 is the first term. We still don't know an so we have to use this formula:
where d is the difference each time ( I already said
it was +6)
an = 12 + (26 -1) 6
an = 162 . Time to plug that into
now you plug in n, an and a1 to finish up =)
Number 6 is done the same way.

From point slope form to y intercept form
http://www.mathwarehouse.com/algebra/linear_equation/point-slope-toslope-intercept-form.php
Here are some things to remember:
When you see anything written in y = mx + b (slope- intercept form), m is
the slope and b is the y-intercept. So if you see y = 3x +2, the slope is 3
and the y intercept is 2. But it has to be written as y equals something x
plus something. So if you have 3x + 2y = 12, you minus 3x from both sides
to get 2y = 12 - 3x. Then you divide by 2 to get y = 6 - 3/2 x and switch
things around to be y= -3/2x +6. Now you know m= -3/2 and b=6 ( or
slope is -3/2 and y- intercept is 6)
Here is a good link about this:

Indirect Proofs
Here is an example from http://www.articlesnatch.com/Article/Indirect-Proof/538980:
Indirect proof is a type of proof that begins by ASSUMING what is to be proved is FALSE.
Then we try to prove that our ASSUMPTION is true. If our ASSUMPTION leads to a
contradiction then the original statement which was assumed false must be true.
Let me explain more in detail.
Suppose you wish to prove statement A is true using an indirect proof.
The first thing you do is:
You assume statement A is false and assume statement A which is a contrary of statement
A to be true.
Then using valid arguments, you arrive at a contradiction (denial or disagreement) to
statement A.
Thus demonstrating that statement A is true.
This concept will be clearer when you look at some examples.
Example 1
Sarah left her house at 9:30 AM and arrived at her aunt’s house 80 miles away at 10:30
AM. Use an indirect proof to show that Sarah exceeded the 55 mph speed limit.
Solution
Suppose that the given statement is false. That is: Sarah did NOT exceed the 55 mph speed
limit.
She drove 80 miles at 55 mph.
At this speed, Sarah would need 80/55 (approximately) = 1 hour 27 minutes to reach her
aunts place.
But as per the problem she drove from 9:30 AM to 10:30 AM exactly an hour.
SO, she must have driven faster than 55 mph, which is a contradiction to our assumption
that Sarah did NOT exceed the speed limit.
Therefore, Sarah exceeded the speed limit.
