Question

Solve the equation t^2-2t+3=0

Answer 1

there are no real number solutions

use the quadratic formula to solve

Answer 2

h = Xv = -B/2A = 2/2 = 1.

K = 1^2 - 2*1 + 3 = 2.

V(h, k) = V(1, 2).
For a parabola that opens upward:
k < 0: 2 real .solutions.
k = 0: 1 real solution.
k > 0: no real solutions.
