Quadratic expression of the form x2 + bx + c
The general form of a quadratic expression is ax2 + bx + c, where a, b and c are constants
a \( \scriptsize \neq 0 \)
a is the coefficient of x2 and b is the coefficient of x and c is a constant term. When a = 1, ax2 + bx + c becomes x2 + bx + c, and is called a simple trinomial .
In general, quadratic equations are raised to the power of 2. It is important to note that there are three algebraic methods of solving quadratic equations.
These are:
- Factorization.
- Method of completing the square.
- Using the factor formula.
- The fourth method is by geometry, i.e. using a graph (graphical method).
The factorization method is considered first.
