Find the error in the following proof that 2 = 1. consider the equation a = b. multiply both sides by a to obtain a 2 = ab. subtract b 2 from both sides to get a 2 − b 2 = ab − b 2 . now factor each side, (a + b)(a − b) = b(a − b), and divide each side by (a − b) to get a + b = b. finally, let a and b equal 1, which shows that 2 = 1.
