Question

a¹/a¹+b¹+a¹/a¹-a¹=2b²/b²-a² solution​

Answer 1

Step-by-step explanation:

We have:

A2−B2=(A−B)(A+B)

and

A2+2AB+B2=(A+B)(A+B)(1)

or

(A−B)(A+B)=(A+B)(A+B)(2)

We either have:

A=−B

or

A−B=A+B

The first equation gives an infinite number of solutions.

The second equation sets B=0 , but we can still choose A .

So we either have:

B=0,A∈R

or

B≠0,A=−B

Where I assume:

A,B∈R

If Matrices are implied by the used notation or some Field where A,B don't necessarily commute the given answer is not correct.

Answer 2

Answer:

a/a¹+b¹+a/a¹-b¹=2b²/b²-a²
