x squared -2x-3 equals 0 is the same as (x + 1)(x - 3) = 0

Yes it is and well done.
(2x-4)(x-1) = 0
3x2 + 2x - 8 = 0 is a quadratic equation.

Yes it is and well done.
(2x-4)(x-1) = 0
3x2 - 2x - 5 = (3x - 5)(x + 1) = 0 gives a solution of x = 5/3 or -1. Was that what you wanted?
3x2 + 2x - 8 = 0 is a quadratic equation.
Yes, it is the only solution.
If: x2+2x-3 = 0 Then: x = 1 or x = -3
2x2 + x - 1 = 0 2x2 + 2x - x - 1 = 0 2x(x + 1) - 1(x + 1) = 0 (2x - 1)(x + 1) = 0 So x is equal either to -1 or 1/2
3x(2x + 1)
It is a quadratic equation.
x = -1 OR x = 3
