Question

I have attached a question from my textbook that I am having trouble with.

Answer 1

Ok. So the first one is

3^2 + 4^2 + (3*4)^2 = (3*4 + 1)^2

the next one

5^2 + 6^2 + (5*6)^2 = (5*6 + 1)^2

Hence

6^2 + 7^2 + (6*7)^2 = what?

and in general

x^2 + y^2 + something = what?

Answer 2

nice work, i couldnt see the pattern

Answer 3
