I am stumped on this problem could someone please help?
Give the solutions to the following quadratic equation by examining the graph of the related quadratic function:
Graph: y=x^2+2x-15
Equation: x^2+2x-15=0
Thanks.

graph it. Look to see where the graph crosses the x axis, that is a "solution". A better word is "root".
