Quadratic equation (in our case ) has the following solutons:

For these solutions to exist, the discriminant should not be a negative number.

First, we need to compute the discriminant : .

Discriminant d=36 is greater than zero. That means that there are two solutions: .

Quadratic expression can be factored:

Again, the answer is: 5, -1. Here's your graph:

x=-1 or x=5
x+2=1 or x+2=7
Therefore, the two integers are -1 and 1 or they are 5 and 7.
