Introduction
Quadratic equations are a fundamental concept in mathematics, and they have numerous applications in various fields, including physics, engineering, and economics. A quadratic equation is a polynomial equation of degree two, which means the highest power of the variable is two. The general form of a quadratic equation is ax^2 + bx + c = 0, where a, b, and c are constants. In this article, we will focus on finding the roots and vertex of a quadratic equation using a calculator.
Understanding the Quadratic Equation
The given quadratic equation is y = -x^2 + 4x + 96. To find the roots and vertex of this equation, we need to use the quadratic formula, which is x = (-b ± √(b^2 - 4ac)) / 2a. In this case, a = -1, b = 4, and c = 96.
Finding the Roots of the Quadratic Equation
To find the roots of the quadratic equation, we need to plug in the values of a, b, and c into the quadratic formula. We will use a calculator to simplify the calculations.

# Define the coefficients of the quadratic equation
a = -1
b = 4
c = 96
# Calculate the discriminant
discriminant = b**2 - 4*a*c
# Calculate the roots using the quadratic formula
root1 = (-b + math.sqrt(discriminant)) / (2*a)
root2 = (-b - math.sqrt(discriminant)) / (2*a)

Finding the Vertex of the Quadratic Equation
The vertex of a quadratic equation is the maximum or minimum point of the parabola. To find the vertex, we need to use the formula x = -b / 2a. In this case, a = -1 and b = 4.
# Calculate the x-coordinate of the vertex
x_vertex = -b / (2*a)
# Calculate the y-coordinate of the vertex
y_vertex = a*x_vertex**2 + b*x_vertex + c
