Question

Find the zeros of f(x) = x2+ x - 6 by using a table and a graph.

Answer 1

The zeroes of the polynomial are the values of x that will make the f(x) = 0. 
 
                                            0 = x^2 + x - 6
Use factoring, 
 
                                            0 = (x + 3) (x - 2)
              
                                        x + 3 = 0 and x - 2 = 0

Thus, the values of x are x = -3 and x = 2.
