Answer:

Yes

........!!!!

Answer 2

Answer:

(A²-B²) = (A-B)² + 2AB

Step-by-step explanation:

a2 + 2ab + b2 = c2 + 2ab Each side of this equation represents the area of the large square. a2 + b2 = c2 Subtract 2ab from both sides. The last equation, a2 + b2 = c2, is called the Pythagorean Theorem. We say “The sum of the squares of the legs of a right triangle equals the square of its hypotenuse.”
