3x2-39x-90 = (3x+6)(x-15) when factored
39x2y326xy4The gcf is 13xy3 .

2x - 3= 9 x=
For x-2x= 3x-43x+1 x-2x= -x and 3x-43x+1 = -40x+1 so -x= -40x+1 subtract -x from both sides 0= -39x +1 -1 = -39x so 1=39x so x=1/39

(2x - 7)(7x + 5)
2x - 3= 9 x=
2 - 39x - 50 = 4 + x -39x - 48 = 4 + x Add 39 x to both sides: -48 = 4 + 40x Subtract 4 from both sides: -52 = 40x Divide both sides by 40: x = -1.3
For x-2x= 3x-43x+1 x-2x= -x and 3x-43x+1 = -40x+1 so -x= -40x+1 subtract -x from both sides 0= -39x +1 -1 = -39x so 1=39x so x=1/39
(7x - 5)(5x - 2)
-38y - 39x (Is that what you were asking for?)
They are three disjoint expressions.
