if A=B

so, A-B = 0 right.?

therefore: => (A+B)(A-B) = A(A-B)

=> (A+B)(A-B) = A(A-B)
——– —-
(A-B) (A-B)

=> Let us A=2 and B=1; therefore; (A-B) is (2-1)
=> so the A-B = 0

=> the solution must be undefine…

On the 2nd triangle there is only 12 squares oocupied by the dark green, yellow, and green figures. That is how you got the HOLE. there are 13 sqaures fully occupied by the length of the red and the green figures on the first triangle.

Um… don’t you mean a(b + c) = ab + ac?
