Completing Square Method

This method Utilizes the power of perfect squares: With the Unknown on the LHS it is posible to find its value Simply by taking the squareroot.

ax^2+bx+c = 0 \Longrightarrow a\left(x+d\right)^2 + e = 0 where e, d are constants \implies x=\sqrt{-\frac{e}{a}}-d

Factoring Method

A quadratic equation of the form x^2+bx+c is factorble into polynomials of degree 1 if and only if its Discriminant is positive and is a perfect square: This x^2+bx+c can be factored into : x^2+bx+c = \left(x+h\right)\left(x+j\right), where h and j are intergers We can obtain the Solution be Equation Either of the Factors to zero: ie:

\left(x+h\right)=0 or \left(x+k\right)=0
