this week in math 10 i learned how to make a trinomial that has the “pattern” ( x^2 , x, #) look “nicer” if it was written out in a jumbled up order. ex  5x-30x^2+40 is written as x, x^2 , # rather than  x^2 , x, #. so we can write it as –30x^2 +5x+40 now, the x^2 is negative so when we find the greatest common factor, we can take -5 instead of +5 to make it positive, which would also switch the other terms to their opposites, so –30x^2 +5x+40 is now -5( 6x^2 -x-40)
