Completing the Square All quadratic equations can be solved by using the Square Root Property by manipulating the equation until one side is a perfect square
Imaginary Unit i defined to be: i^2=-1
Pure Imaginary Number square roots of negative real numbers
Square Root Property the sum of squares can be factored over the complex numbers
Complex Number terms are not like terms and cannot be combined
Complex Conjugates two complex numbers in the form of a+bi and a-bi
Factored Form 0=a(x-p)(x-q)
FOIL Method use this method to write a quadratic equation that is in factored form, in standard form; uses the distributive property
Quadratic Equation equations that are set equal to a value
