Types of Quadratic
A quadratic expression is functions of the form ...
where , and are constants.
or, factorised ...
which is a factorised version of the first, where , , and are constants.
or, completed square form ...
again another version of the first, where , and are constants.
Fully factorise the following:
(Hint: always look for a common factor first, if available, then check if other forms of factorisation are possible)
How many integer values of are there for which is factorisable? How about ?
