Distributive property
a(b+c)+ab+ac
a(b-c)=ab-ac
(6z^2-4z+1)(8-3z)
move for nicety
(8-3z)(6z^2-4z+1)
distribute
8(6z^2-4z+1)-3z(6z^2-4z+1)=
48z^2-32z+8-18z^3+12z^2-3z=
-18z^3+48z^2+12z^2-32z-3z+8=
-18z^3+60z-35z+8
        
             
        
        
        
Photo math works and the answer would be on that app!!
        
             
        
        
        
1000 because 100 divide my 10 is 10 so just add a zero
        
             
        
        
        
We can reject the last one: subtracting a non-zero value will result in a smaller value. 
So now we have: 
<span>2(A + B)
 (A + B)2
 A2 + B2
If all of them are mulptiplications, then they are all equivalent!
I mean by this, if what you meant is this:
</span>
<span>2*(A + B)
 (A + B)*2
 A*2 + B*2
If there is no sign, then the multiplication sign is implicit, 
and all of these expressions say exactly the same: two of A and two of B.
</span>
