What are the properties of quadratic function?
In terms of the variable "x" it has terms added together which
are constants (eg 1,29,100 etc), linear terms (eg x, 4x, 126x etc)
and quadratic terms (eg x2, 6x2, 43x2 etc) and no others. Example
24+5x+3x2. It can always be factorized into the product of two
linear expressions k(x+a)(x+b) where the constants may be real,
imaginary or complex.
