    Solve Quadratic Equation: 2x^2 - 3ax - 3bx + a^2 + b^2 + 2ab = 0

    I know quadratic equations, but I'm getting stuck here, because I do not know how to solve for x. I did establish the fact that 2x^2 -3(a+b)x + (a^2 + 2ab + b^2) = 0 is correct because it follows ax^2 + bx + c. Could you please help me out?

    Solve Quadratic Equation: 2x^2 - 3ax - 3bx + a^2 + b^2 + 2ab = 0

    Need help solving some. I'll put up one for now. a/b-x + b/a-x = 2 I'm just looking for how to solve it, because I always reach 2x^2 - 3ax - 3bx + a^2 + b^2 + 2ab = 0 and get stuck. Please show me your steps. Thanks!

    High School How does a generator produce AC current?

    I don't have the apparatus. So the coil changes directions? It starts moving in clockwise, and then changes to anticlockwise? Im still so confused =/

    High School How does a generator produce AC current?

    I just don't understand how it does, because I never noticed the terminals change positions. I understood how DC generators work, but not AC.
