Does this look correct @gezimbasha
Sorry to bother you

Answer 2

Yes, they are factors. It is correct. But what's the thing with the difference of two squares?

Answer 3

I dont know. maybe like this or not.

a) 45 = 7^2 - 2^2 = (7 + 2)(7 - 2) = 9 * 5

b) 77 = 9^2 - 2^2 = (9 + 2)(9 - 2) = 11 * 7

c) 112 = 11^2 - 3^2 = (11 + 3)(11 - 3) = 14 * 8

Answer 4

Yeah this one looks more like it. You're pretty good at this aren't you?!
