(a+b)2 −c2 ( a + b) 2 - c 2 Since both terms are perfect squares, factor using the difference of squares formula, a2 −b2 = (a+b)(a−b) a 2 - b 2 = ( a + b) ( a - b) where a = a +b a = a + b and b = c b = c. (a+b+ c)(a+b−c) ( a + b + c) ( a + b - c) WebThe result: (a−b) 2 = a 2 − 2ab + b 2. If you want to see why, then look at how the (a−b) 2 square is equal to the big a 2 square minus the other rectangles: (a−b) 2 = a 2 − 2b (a−b) − b 2. = a 2 − 2ab + 2b 2 − b 2. = a …
