I need help with this math problem?

http://schoolisland.com/review/Courses/MasterMath/... that's the diagram

In the diagram of circle O, chords and intersect at E.

AE=X

EB=X+1

CE=X-1

ED=2x

I can't figure this out, help me

I need the answer before 11:58

Update:

I need to solve for X so that I can find the lengths of the chords

Update 2:

The Formula is (AE)(EB)=(CE)(ED)

Update 3:

The Furthest I've gotten is X^2-X=0 can I do anything with that?

    So what do u need to figure out. This is just the data no question is presented here.

    here you go

    AE/EC= EB/ED

    chords of a circle interesect in equal proportions

    X/X-1 = X + 1/2X

    2X2 = X2 - 1

    X2 + 1 = 0

    this means X = i i.e. square root of -1... I have some doubts on the answer myself. pls cross check the theorem and the question (values of the sides)

    I dont know what you are supposed to find.

    you can derive that

    ab = 2x+1

    cd = 3x-1

    but What that gets you ?

    if the chords are equal then 2x+1 = 3x -1

    1 = x -1

    x = 2

    This looks similar to some stuff I've recently seen. If I'm not mistaken, you should be able to solve this using the quadratic equation. There's tons of quadratic solvers on Google if you need them.
