Problem
Shapes 5 asmyn plays in the outfield on her softball team. She throws a softball at a rate of \( 2(t-2)(t+5) \). How Eraser much time will the softball spend in the air? (Hint) Find the \( x \)-intercepts.
Solution
Step 1 ：Find the x-intercepts by setting the equation to zero: \( 2(t-2)(t+5)=0 \)
Step 2 ：Solve the quadratic equation: \( (t-2)(t+5)=0\)
Step 3 ：t-intercepts are the solutions of the equation: \(t=2\), \(-5\)
