Answer 4

Thank you Damon this helped a lot!

Answer 5

It has complex roots so I bet you have a typo

0.25 + 2.2220486043289i
0.25 - 2.2220486043289i
It has Complex Roots !

Answer 6

I bet they mean:
2x^2 - x - 10 = 0?

Answer 7

h = Xv = -B/2A = 1/4 = 0.25.
k = Yv = 2(1/4)^2 - 1/4 + 10 = 9 7/8 = 9.9.
V(h, k) = V(0.25, 9.9).
k > 0. No solution.
