<span>To find the average number of muffins baked by both the girls, wed need to find the total number of muffins baked by the girls together. Number of muffins baked by Andrea = h - -- - - - - -- ------------------- by violet = h-8 ( 8 fewer than h means h-8) So the total number of muffins = h + h - 8 = 2h-8 To find the average, divide the total by the number of people(2) = 2h-8 /2 = h - 4</span>

This is the concept of algebra, the average number of muffins baked by each girl will be given as follows;
Muffins baked by Andrea=h muffins
Muffins baked by Violet =h-8

Average=(Total sum of numbers)/(Number of items)
total sum=h+(h-8)=2h-8 
Number of items=2
thus;
average=(2h-8)/2=h-4
the answer in terms of h is (h-4)

1. your leading coefficient has to be 1 (nothing before the x^2). If there is you have to divide that out before you start.
2. Move your constant (the number without any x attached) to the other side of the equation
3. take 1/2 of the b term (the one with the x attached) and then square it and then add it to both sides
4. Factor the left side
5. Set each factor equal to 0 and solve

Here is an example:

4x^2-24x+20=0
The first term is not a 1 so we have to divide it out by 4 first
x^2-6x+5=0
Move the 5 to the other side.  It becomes negative.
x^2-6x=-5
Take 1/2 of 6 (3) then square it (9) and add it to both sides.
x^2-6x+9=-5+9
Factor the left side
(x-3)(x-3)=4
(x-3)^2=4
To solve you need to square root both sides
x-3=+/-
x-3=+/-2
x=3+2=5
x=3-2=1
Those would be your two answers.
