p = $300
Answers:

where 'a' cannot be zero.

Explanation:
The vertex is (h,k)
The x coordinate of the vertex is h which is found through this formula

For example, if we had the quadratic
, then we'll plug in a = 3 and b = -6 to get: 
------------
To find the value of k, we plug that h value into the original standard form of the quadratic and simplify.


It's interesting how we end up with the numerator of
which is similar to
found under the square root in the quadratic formula. There are other ways to express that formula above. We need
to avoid dividing by zero. The values of b and c are allowed to be zero.
Answer:
7x^2 + 14x - 12
Step-by-step explanation:
Add like terms:
(4x + 8x - 5) + (3x2 + 6x - 7) becomes:
4x^2 + 8x - 5 or (grouping like terms in columns):
+ 3x^2 + 6x - 7
---------------------
7x^2 + 14x - 12
The savings is the amount taken off or 32% of 150
32% of 150 is 0.32 times 150=48
savings is $48
or you can do
150/100=x/32
cross multiply to get
x=48
so savings is $48
