Solve Quadratic Equations with Alpha1 x Beta1 and Alpha2 x Beta2"

[kasot.tope]

express the following in terms of alpha1 x beta1 and alpha2 x beta2

alpha1 x alpha 2=beta1 x beta2

 

[HallsofIvy]

\alpha_1\alpha_2= \beta_1\beta_2 gives
\frac{\alpha_1}{\beta_1}= \frac{\beta_2}{\alpha_2}

or \alpha_1\beta_1^{-1}= \alpha_2^{-1}\beta_2

but there is no way to express it in terms of the products \alpha_1\beta_1 and \alpha_2\beta_2.

Well you can still find out what \alpha_1\beta_1 is equal to in terms of the 4 variables.

start with \alpha_1\alpha_2=\beta_1\beta_2 and multiply both sides by \beta_1

That's like using a word in its own definition, but yes, it can be done.

 

[Mentallic]

Either that or we have to break it to the OP that we can't define that word

hmmm... i still need some one to help me with it

kasot.
There must be more to this problem. You are asking us to express an equality "in terms of" parts of that equality. It can be done, but we might be more helpful with more information.
1) where is this from?
2) is English your native language?
3) what course/class is this for?

1) it is a question i saw in a test book am studying and it is not my course work
2) NO, BUT IT IS MY OFFICIAL LANGUAGE
3) it for general maths

Then my response would be your best bet at getting an answer.
