Example 1:Use completing the square method to solve: x2- 4x - 5 = 0. Solution: Let us transpose the constant term to the other side of the equation: x2- 4x = 5 Now, take half of the coefficient of the x-term, which is -4, including the sign, which gives -2. Take the squar...
If the square root term is irrational, then the two roots are a conjugate pair.If we call those two roots r1 and r2 , then the quadratic can be factored as(x − r1)(x − r2).We will prove the quadratic formula below.Example 4. Use the quadratic formula to solve this quadratic ...

In this example, there is no constant term to move. Step 2: Factor out the lead coefficient in order to make the new lead coefficient equal to 1. In other words, divide each term bya, placing the original lead coefficient outside the parentheses. Step 3: To complete the square we must...

Applying what is learned in the class is very vital in fact it is a process TEKS that teachers need to use to maximize student’s understanding. “When are we going to use this in real life?” and “Why do we need to know this?” are questions that students ask on a daily basis....
For example, when a positive constant C is added to a function, the new graph moves C units up. If a positive constant C is added to the independent variable of a function, the graph is obtained by moving the basic graph C units to the left. In this same se...
