The Balylonians (around 400BC) first developed the algorithmic method for completing the square. But they didn't do it using equations, which they had no concept of, just a set of rules for particular cases. The Greeks, such as Euclid, showed geometrical proofs of the method. But it wasn't until the Persian mathematician al-Khawarizmi in the 9th century that the general algorithm was written down. Even this wasn't done using symbols like we use in algebra today but written out in prose.

What equation results from completing the square and then factoring?
A quadratic equation
What is the principle square root of 64?
The principle square root of 64 is ±8.8.* * * * *The square roots of 64 are +8 and -8.The PRINCIPAL square root is the positive root, +8.So, the answer to the question that was asked is +8 not ±8.
Solving quadratic equation by completing the square?
Yes it is quite possible
Definition of principle square root?
The square root of a positive real number can either be +/-. The principle square root is defined as the positive value. sqrt(9) is +/- 3, but the principle square root of 9 is 3. For complex numbers the principle square root is the argument (or angle) of the complex number that lies between (-pi,pi]. I am pretty sure that the upper angle pi is closed while the lower angle -pi is open, but not 100%.
Can all quadratics be solved by completing the square?
Completing the square is one method for solving a quadratic equation. A quadratic equation can also be solved by factoring, using the square roots or quadratic formula. Solving quadratic equations by completing the square will always work when solving quadratic equations-You can also use division or even simply take a GCF, set the quantities( ) equal to zero, and subtract or add to solve for the variable
