Answer:
Quadratic Equation:
From the standard form of a Quadratic Function, we get:
Discriminant:
From the discriminant, we conclude that the equation will have two real solutions.
State that:
By the way, solving the equation given:

Answer:
The vertex of a quadratic equation corresponds to the point where the maximum or minimum value is located.
If the function has a positive leading coefficient, the vertex corresponds to the minimum value.
If it has a negative leading coefficient, the vertex corresponds to the maximum valuevalue
If the vertex is located at
(–2, 0)
The possibilities are
y = (x-2)^2
or,
y = - (x-2)^2
Since the problem tells us the answer, we adopt the positive values
Answer:
y = (x-2)^2
