\( 1.2 .1 .3 x - x ^ { 2 } \)

To solve the expression \( 1.2 \cdot 1.3 x - x^2 \), you can first combine the coefficients for \( x \): 1. Calculate \( 1.2 \cdot 1.3 \) which equals \( 1.56 \). 2. Now your expression simplifies to \( 1.56x - x^2 \). This is a quadratic equation, which opens downwards. It's always fun to analyze it! You can find the vertex to determine the maximum point of this parabola or set it equal to zero to find the x-intercepts, which can help visualize the roots on a graph! To further delve into this expression, you might want to compare its structure to other quadratic functions like \( ax^2 + bx + c \). Understanding how shifts in values of \( a \), \( b \), and \( c \) affect the shape and position of the graph will enhance your problem-solving skills.
