B. Quadratic function defined by y = x + bxc can be transformed into the
form y = a(x - hpk (called the Vertex Form), by using Completing the
Square Method. The following steps can be followed.
1. Group together the terms containing x
2. Factor out a. If - 1. proceed to step 3.
3. Complete the expression in parenthesis to make it perfect square trinomial
by adding the value of pand subtracting the value
al P to the constant term.
4. Simplify and express perfect square trinomial as the square of
binomial​
