-b/2a is the formula to find the vertex of a parabola. If one of the intercepts is at (-b/2a + 3, 0), the other one must be at (-b/2a - 3, 0), since the two x-intercepts have to be the same distance from the vertex.
From points (2, 0) and (6, 0), you can get base = 6 - 2 = 4.
From point (8, 5), you get a height of length 5.
A = bh/2 = 4 * 5/2 = 10
Area = 10 square units
