Final Chapter in Polynomials

We learned how to deal with the bad looking polynomials

 

When we look at this question, we see the coefficient 5. As the leading number. We see the y variable in the middle(just ignore that.)

We look for any common ground to divide. 

If there’s none we look for difference of squares.

Then we move on to solving the question.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

There are multiple ways of solving math questions like this,

the one I prefer and that I sue is to get rid of the 5 then multiple the 5 to 7

x*2+2y-35

that way we have x*2 by itself, so then we realize that we can achieve 2 by 5 and 7 as it also gets 35
