    Let x = y
    Multiply by x: x^2 = xy
    Subtract y^2: x^2 - y^2 = xy - y^2
    Factor: (x + y) (x - y) = y (x - y)
    Common term (x - y) on both sides, so cancel it out.
    Leaves: x + y = y
    But x = y, so substitute to get: y + y = y
    Combine: 2 y = y
    Common term (y) on both sides, so cancel it out.
    2 = 1

    Common term (x - y) on both sides, so cancel it out...

    Or not.

    It was the common term line. You can't divide by zero. Since x=y, x-y = 0.

    BTW, my degree is bachelors of science in civil engineering, but I love math, physics, and chemistry. Totally a nerd.

    Actually, one could have stopped at the "Factor: (x + y) (x - y) = y (x - y)" line and ignored the "Factor" part.

    (x + y) (x - y) = y (x - y)
    Since x=y, x - y =0
    ergo
    (x + y) (0) = y (0)
    0 = 0

    This is a problem I have given my kids for error analysis. It takes a little while, but they usually get it.

    I don't think you could stop there since 0=0 is still a true statement. It's not till you violate the rules of math that we get into trouble.

    OOPS! I was referring to the original problem posted for the kiddos to fix. Sorry I was unclear.

    i have always been a major science nerd. I even built my own TESLA COIL. im also working on my degree in Renewable energy. AAS

    im not a science nerd.
    but im wildly attracted to nerds and geeks, so that should count for something.

    that's just weird...

    ...and if you hold on a second, i think i can prove so mathematically!

    :happy:

    Ooooohhhhh! I want a Tesla Coil. I don't know what I'd use it for, but it looks cool. I tried to build a Van de Graff generator when I was younger...unfortunately it was a failure. I didn't know at the time exactly what materials you needed to use as the pulleys for the belt. How sad.
