8-21.

Solve

*x*^{2}+ 2*x*− 5 = 0. Homework Help ✎How many

*x*-intercepts does*y*=*x*^{2}+ 2*x*− 5 have?Approximately where does the graph of

*y*=*x*^{2}+ 2*x*− 5 cross the*x*-axis?

You could complete the square, find the vertex, and consider the orientation to determine if this parabola has 0, 1, or 2 *x*-intercepts.
