a = b
a = b
a^2 = ab a^2 - b^2 = ab - b^2 (a+b)(a-b) = b(a-b) a+b = b 2b = b 2 = 1 1 = 0 ¬¿¬ |

Dividing with zero is a no no. [/ QUOTE ] (a+b)(a-b) = b(a-b) a+b = b... COMPUTER ASPLODE! I first saw this trick in my high school calculus class. Watching the other kids try to figure this out was +HARHAR. |

Isn't the problem in step 4?

Isn't the problem in step 4? [/ QUOTE ] The problem is in between these two lines: (a+b)(a-b) = b(a-b) a+b = b Reducing the equation as above is dividing both sides by (a-b). (a-b) is also (a-a) or 0. Dividing by zero is not defined on the real number system. As someone already mentioned - it's a big no-no. rabbit |

Isn't the problem in step 4? [/ QUOTE ] Yeah, I wasn't really clear about that... it is the dividing both sides by (a-b). |
