    Solving a quadratic equation with 2 square values

    Hi i am having some difficulty in solving the below quadratic equation.

    The question asks me to obtain the solution of the following quadratic equation


    s2 + 2a b2 s + s2


    What i dont undrstand with this question is that i have two values which are squared (s,b)

    Hope this makes more sense

    Thanks
    Richard



    Many thanks

    Hi Richard,

    First of all, you don't have an equation. There's no "=" sign.

    This is what you have written: s^2+2ab^2s+s^2. All we can do is simplify it. Check your problem again and see if you've missed something

    Richard,

    All we can do here is simplify the expression. There is nothing to solve. Here is all we can do.

    s^2+2ab^2s+s^2

    2s^2+2ab^2s

    2s(s+2ab^2)

    That's it. Are you certain you copied it correctly?

    Quadratic equation

    Im awful sorry i have written the formula down wrong

    what it should have typed

    s2 + 2abs + b2

    Still doesnt have a = sign on it

    Is it just simplying the equation like you said with the last reply

    Thanks again

    Richard,

    This is an expression, not an equation.

    s^2+2abs+b^2

    I am still suspect about the way this thing looks. There are no common factor in this expression. It cannot be simplified further.

    Are you sure about the middle term being +2abs? Because, if you get rid of the a, you would have this:

    s^2+2bs+b^2

    which factors into this:

    (s+b)(s+b) \ \ or \ \ (s+b)^2

    But, I'm guessing here and I don't like to do that.

    all i ve done is substituted a b, as the original expression is mathamatics symbols which im unsure on how to put them on here.
    If i can get access to a scanner ill send a attach sheet maybe easier.

    But thanks anyhow
