Question 47462: Deart Sir:
I'm having a hard time with this problem, which is not from a textbook:
factor this equation--
18mn^2 - 81mn^2x + 243mn^3x^2
After many tries I came up with this, but I'm at an impasse:
9mn^2(2 - 9x + 27mnx^2)
Could you give me some direction, please?

You can put this solution on YOUR website!
18MN~2-81MN~2X+243MN~3X~2 OR 9MN~2(2-9X+27NX~2) YOU FORGOT THAT YOU FACTORED OUT THE M FROM THE LAST TERM ALONG WITH THE 9 & THE N~2
