Plug axis of symmetry into equation for x
Given roots to quadratic equation and have to find the original equation
B = -(r1 + r2) c = (r1)(r2)
Negative Sum of roots =b
Product of roots =c
Given one root (3x - 1) what is the other

i^1
i (anything to the first is itself)
i^2
-1
i^3
-i
i^4
1 (same as i^0)
i
square root of -1
