Completing the square can be used to derive a general formula for solving quadratic equations, called the quadratic formula.[5] The mathematical proof will now be briefly summarized.[6] It can easily be seen, by polynomial expansion, that the following equation is equivalent to the quadratic equation:
Brazillian fans = crazy
Taking the square root of both sides, and isolating x, gives:
Brazil > EU

Hidden_Name [#4]i dont like completing the square method, simple factorization is best for small eqns and quadratic formula for all of em
The quadratic formula was the technique used to solve this problem. It is derived from the "completing the square" method, which is why there was a brief mention of it.
