Answer:
See below
Step-by-step explanation:
You cannot find two whole number integers that give a sum of -12 and a product of 6.
-1 + -11 = -12, but (-1)(-11) = 11, which isn't 6
-2 + -10 = -12, but (-2)(-10) = 20, which isn't 6
...and so on...
 
        
                    
             
        
        
        
Ab = (7x-6) →   b = (7x-6)/a   (1)
bc = (12-2x) → b = (12-2x)/c   (2)
Since (1) = (2) → (7x-6)/a = (12-2x)/c OR  a/c = (7x-6)/(12-2x)  (3)
Multiply  both numerators of (3) by the SQUARE of their  respective denominators;
(a*c²)/c = (7x-6)(12-2x)²/(12-2x)
Now simplify:
ac = (7x-6)(12x-2x)  or ac = -14x² + 96x - 72
