Question
I'm not sure how to factor this
The image contains a mathematical function written as:

\[ F(x) = 12x^2 + 48x - 96 \]

This function is a quadratic expression, which is a polynomial of degree 2. The standard form of a quadratic equation is \( ax^2 + bx + c \), where \( a \), \( b \), and \( c \) are constants. In this expression:

- \( a = 12 \)
- \( b = 48 \)
- \( c = -96 \)

The graph of this function would be a parabola. Since the coefficient of \( x^2 \) (the term \( a \)) is positive, the parabola will open upwards.

### Key Features:
- **Vertex**: The vertex of the parabola can be found using the formula for the x-coordinate: \( x = -\frac{b}{2a} \). The y-coordinate can be found by substituting this x-value back into the function.
- **Axis of Symmetry**: The vertical line that passes through the vertex, given by \( x = -\frac{b}{2a} \).
- **Roots**: Solving the equation \( 12x^2 + 48x - 96 = 0 \) will give the x-intercepts (if they exist), known as the roots of the equation.
- **Y-Intercept**: The point where the graph intersects the y-axis, found by evaluating \( F(0) \), which gives the constant term \( c = -96 \).

Understanding the characteristics of this function can provide insights into its behavior and graphical representation.
