Most textbooks interpret standard form of a quadratic function to be as follows:
f(x) =
In the function f(x) =
, notice we do not have a value for "c". Just place a "0" in for the c and you have standard form.
the criteria for standard form:
1. All like terms are combined
2. Degree must drop from left to right
3. The leading coefficient cannot be equal to zero.

Answer:
Step-by-step explanation:
The picture of the question in the attached figure
step 1
Find the area of the large square
step 2
Find the area of the smaller white square
step 3
Find the area of the blue region
Subtract the area of the smaller white square from the area of the larger square
step 4
Find the probability
we know that
To find out the probability that a point chosen at random is in the blue region, divided the area of the blue region by the area of the larger square
so
Simplify
