How to Solve a : Factoring the Unfactorable

Hi everyone, today I am going to show you how to solve a factoring the unfactorable, question:

Check list for solving a IS equal to one

• Step one: Subtract the first number, to both side
• Step two: Divide the middle term by 2, then square it, and add the number to both side
• Step three: Take the square root of both side. (don’t forget the + or – constant)
• Step four: Isolate the variable
