What are the factors for x squared - 18x + 8

Alright so you have

You would think to factor this that you need to find two numbers that add up to the coefficient of the middle term (-18) and multiply to the last term (8).
But this is not factorable

So to solve the equation  you have to use the quadratic formula, which is 

This polynomial is already in standard form , where a is -18, b is -18, and b is 8, so just plug the numbers into the equation.

So you get , 

Cbecause they are equal so that means it is the same on both sides? ! hope this
