Find the following product. Use the vertical multiplication method.
(9x - 1)(x2 - 4x + 1)
9x3 - 35x2 + 5x - 1
9x3 - 36x2 + 9x + 1
9x3 + 37x2 - 13x + 1
9x3 - 37x2 + 13x - 1

(9x - 1)(x2 - 4x + 1)
= 9x^3 -36x^2 +9x -x^2 +4x -1
= 9x^3 -37x^2 +13x -1

Not sure what vertical multiplication method implies but.
(x2-4x+1) * (9X-1) =
9X3-36X2 + 9X
- (X2 - 4X +1)
= 9X^3 -37X^2+13X -1

alane, you've asked 9 eight-grade math questions in the past half-hour. Are you cheating on a homework assignment or on a test?

I believe he, or she, is cheating.
But this isn't the smartest way because you could wait an hour for one answer.
Are you in summer school? Cause it's almost the end of June.
