Question

prove 1=2 using variables

Answer 1

Answer:Assume that we have two variables a and b, and that: a = b. Multiply both sides by a to get: a2 = ab. Subtract b2 from both sides to get: a2 - b2 = ab - b. This is the tricky part: Factor the left side (using FOIL from algebra) to get (a + b)(a - b) and factor out b from the right side to get b(a - b).May 16, 2014
