x2 - 12x3 = x2(1 - 12x)
x2(x-4)
Assume an additive expression.X5 + X3X3(X2 + 1)--------------------so,X3====Is the LCD
multiplication
6x3
You can expand (x + y)2 into x2 + 2xy + y2
The product is 36
factor
The GCF is 4.
4554
12x3 then divide by 4
I'm going to assume x3 is x3 and then you have 2x(1+6x2). Another reading is that 12x3 is 36, in which case you get 2(x+18).
36x1 13x2 12x3 9x4 6x6
