[SAT math] factor by complete square

Factor Theorem and Quadratic Formula are powerful tools for factoring, but they do have their disadvantages…
That is, the amount of calculation and the number of trials can be enormous when the coefficients and constants are large numbers.
In some cases, the calculation is extremely difficult or guessing factor is absolutely impossible…

In this video, I will introduce factoring using Complete the Square, which could avoid the disadvantages of the Factor Theorem and Quadratic Formula.

By using this factoring method and combining it with a variety of techniques, you will be able to factor some difficult math questions!
