    x^2-x+6 to solve this you will need to make it into two parenthesis

    to do this you need to make both parenthesis when multiplide equal the samething you started with, it will get easier to understand as i get into it

    so we have ( , ) ( , ) blank parnthesis, so lets begin with the x^2 (x, ) (x, )

    since we have 2 x's we can spead it evenly accross the parenthisis

    -x^2-x+6 first before we seperate it we need to take out the negative in from of x^2 if we dont they will contradict later in the problem
