In mathematics, completing the square is a technique for transforming a quadratic equation into a form in which the coefficients of the quadratic term are zero, one, or negative. The resulting quadratic equation is called a "completed square".

In mathematics, a radical is a function that extracts square roots. The term is also used for a symbol that represents such a function, usually the symbol ?, which is called the radical sign or radix. In algebra, radicals are represented by square root symbols.

In mathematics, the quadratic equation is a polynomial equation of degree two. It is of the form ax^2+bx+c where a,b,c are called the coefficient of the quadratic term. The solutions to this equation are called quadratic equations or quadratic pairs, and the corresponding solutions are called quadratic solutions or quadratic roots.
