Hope this helps.
In the second problem, because 3 is not large enough to subtract 6 from, change 4 to 3 and add 1 before 3 to get 13-6.

Answer:
x= 130 degrees
Step-by-step explanation:
Quadratic f(x) = (x -h)² +k has vertex (h, k) and axis of symmetry x=h. When k is negative, the number of real solutions is 2, because both branches of the function cross the x-axis.
In your equation, h = -3 and k = -8.
Axis of symmetry: x = -3
Vertex: (-3, -8)
Number of real solutions: 2
