In this video I work through 68 examples of factoring quadratic expressions when a is not equal to one. The first couple of examples I explain the process of factoring by using the ac method and box ...

To factor a trinomial in the form of x squared plus bx plus c, we use the same exact method as the ac method. So, bear with me for a little while and then I’ll show you the shortcut. In order to use ...

we find two factors of the product of the constant term (the term with no variable) and the coefficient of the squared variable whose sum gives the linear term. These factors are now placed in ...
