You can put this solution on YOUR website!
For any given graph of a quadratic such as %28x%5E2%29%2B2x%2B4 the 'solutions' are typically x values that make that graph zero. Thus you are looking for the x values when y = 0.
In the graph below your 'solutions' are x=2 and x=-1 since that is where the y values are 0
