1. ## 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

the question doesnt have a = sign. is this the problem i have to solve do you think?

Thanks
Richard

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?

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.

7. 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
