Evaluate the problem

Question

If A?B=A^2+AB+B^2, evaluate 4?3

Answer 1

Plug into the right side: A=4, B=3.

 

You get 4² + 4•3 + 3² = 16+12+9 = 37, so that's what 4?3 is [question mark being the mysterious operation on A and B specified by the right side of A?B=A^2+AB+B^2.

Answer 2

What does the "?" represent? The wording of the problem is very unclear. I THINK you're being asked to substitute 4 for A and 3 for B... is that right?
