Simplify: (4a−2b)(a+b) 4a2−8ab−2b2 4a2−6ab−2b2 4a2+2ab−2b2 4a2−2ab−2b2

Step-by-step explanation:

4a^2 + 4ab - 2ab - 2b^2

4a^2 + 2ab - 2b^2

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
