Question

Find the Value of A^2
If, A + B = 16. A - B = 8. Then what is the value of A^2?

Answer 1

You have two equations; let us add the two equations

A + B = 16
A -  B = 8
---------------
2A = 24
---------------

Solving this further gives us the value of A = 12.

Now let us try to find the answer to our question. We have been asked to find the value of A².

Since A = 12; A² = 144; and this is our answer.
