(3x+4)(x-2) 3x2 -6x+4x-8 3x2-2x-8
5x7 - 2x9 + 5x or written properly, -2x9 + 5x7 + 5x
72 i guess!
3x2-y=6 3x2-y=6
7x9 is the multiplication fact that can be found using the arrays 2x9 and 5x9.
While it is possible to factor 3x2 from both of these and get 3x2(4 - 1), it's a lot easier to subtract 3x2 from 12x2 and get 9x2
3x2-27 is equal to -21.

Yes. (Assuming that -3x2 is the best representation of 3x2 that this browser will allow.)
There are no prime factors in that equation.

5x-2x=9
