Algebra.Com's Answer #323620 by richard1234(7193)![]() ![]() You can put this solution on YOUR website! Expanding the left hand side, we get a^2 + 2ab + b^2, which is supposedly equal to a^2 + b^2. This implies that 2ab = 0 for all a,b. To obtain a counterexample to this statement, simply choose some nonzero a,b e.g. a = 5, b = -2 and it will contradict the claim. \n" ); document.write( " |
