Completing the Square

Earlier we talked about square quadratic polynomials of the forms (x + α)(x + α) and how these expand to become of the general form:

The roots of the quadratic polynomial above are - and - from

which means that

The above is easy to solve, by taking the square root of both sides of the equation such that

which means that

but since a quadratic polynomial must have 2 roots, we say that

which is better written as
