Answer: 
b
Step-by-step explanation: 
(a - b)² = a² - 2ab + b²
(2x - 6)² = (2x)² - 2*2x *6 + 6²
              = 4x² - 24x + 36
 
                                
             
                    
              
Answer: b
Step-by-step explanation:
(2x-6)^2
(2x-6)(2x-6)
(2 X times 2x = 4x^2
(2x times -6 = -12x
-6 times 2x= -12x
-6times -6 = 36
So you get 4x^2-12x-12x+36
Combine the x's. You get 4x^2 -24x+36
