There has to be a mistake!

                                                      

You think you know Algebra.  Below is an Algebraic proof.  If there is not a flaw somewhere in this proof, then we have proved that 1 does equal 2.  E-mail Mrs. Zimmermann what the flaw is and receive a Fibonacci Point.

Text Box: Statement Reason 1. a, b > 0 1. Given 2. a = b 2. Given 3. ab = b2 3. Multiplication Property of Equality (step 2) 4. ab – a2 = b2 – a2 4. Subtraction Property of Equality (step 3) 5. a(b – a) = (b + a)(b – a) 5. Factoring (step 4) 6. a = (b + a) 6. Division Property of Equality(step 5) 7. a = a + a 7. Substitution (steps 2 & 6) 8. a = 2a 8. Addition of like terms (step 7) 9. 1 = 2 9. Division Property of Equality (step 8)
