x=0
4x2 - 2x = 0
Assuming that 4x2+2x = 0: 2x (2x+1) = 0 2x = 0 or 2x+1 = 0 x = 0 or -1/2
2x - 1 = 0 2x = 1 x = 0.5
4x2-2x = 0 2x(2x-1) = 0 x = 0 or x =1/2
If -2x +14 = 0, -2x = -14, or x = 7.
-2x+16 = 0 -2x = -16 x = 8
Which means 0 = -1!
y=2x y-2x=0 or 2x-y=0
2x - 4x + 3 = 0 -2x + 3 = 0 2x = 3 x = 3/2 = 1.5
x squared -2x-3 equals 0 is the same as (x + 1)(x - 3) = 0
4x2 - 2x - 3 = 0 (2x + 1)(2x - 3) = 0 x = -(1/2) or (3/2)
