Quadratic equations can be simplified by factoring it into <math>(x + r)(x + s)</math>, where <math>r + s</math> equals B in <math>y = x^2 + bx + c</math> and <math>rs</math> equals <math>c</math> in the above equation.<ref>http://www.regentsprep.org/regents/math/algtrig/ate3/quadlesson2.htm</ref> Equations that cannot be easily factored this way can become easy to factor by completing the square.
