See below
Explanation:
For the vertex, we need to get our equation in standard form. Using FOIL, it can be rewritten as
The y-coordinate is found by plugging our answer back into the equation:
Vertex:
By "intercepts", I believe you mean both the x-intercepts and the y-intercept. For the x-intercepts, we can use the factored equation, set
X-intercepts:
To find the y-intercept, we will use the standard form of our equation, set
Y-intercept:
