X^2 + 8x + 7 = 0
x^2 + 7x + x + 7 = 0
x(x + 7) + 1(x + 7) = 0
(x + 7) (x + 1) = 0
x = -7      or       x = -1

Answer:
6 units²
Step-by-step explanation:
The coordinates (1,1) (1,4) (5,1)  form a right triangle as shown in the graph below
The base is  is (1,1) and (5,1) so the length is 5-1 or 4 units
The height is (1,1) and (1,4) so the height is 4-1 or 3 units
Area of a triangle is given by
A = 1/2 bh
     = 1/2 (4*3)
     = 1/2 *12
     = 6 units^2
