Question

What are the zeroes of a quadratic function and how are they found?

Accepted Answer

if/where the function crosses the *x*-axis (*x*-intercepts)   
    
Set the function equal to 0, factor (use quadratic formula if necessary), and solve for *x*.    
The correct values of *x* will yield a true statement when plugged back into the equation.
