Which option correctly shows how this formula can be rearranged to isolate x^2? Options in picture.

A

Step-by-step explanation:

We have:

And we want to isolate x₂.

So, let’s first remove the denominator by multiplying both sides by it:

The right side will cancel. This will leave:

Now, we can subtract x₁ from both sides. So:

Finally, we will multiply both sides by -1. So:

Hence, our answer is A.
