a² + a² - 2ab = ab + a² - 2ab
2a2 - 2ab = ab - 2ab + a2 surely though ab-2ab=-ab so you saying ab-a^2, not a^2-ab. isn't correct isn't it?, and yeah that now changes it to 1=0... spooky |

The scary part of that, is I understand it.
2(a^2 - ab) is really: 2x1 and a^2 - ab is 1 - 1 so the answer is really 1=0 |

There is...at the second to last step you shuld have 2(a^2-ab), and that's right, but if you're putting a^2 on the right it would be ab-a^2, not a^2-ab. |

let a = b
a² = ab Multiply both sides by a a² + a² - 2ab = ab + a² - 2ab Add (a² - 2ab) to both sides 2(a² - ab) = a² - ab Factor the left, and collect like terms on the right 2 = 1 Divide both sides by (a² - ab) I'm pretty sure there is something wrong with this. |
