Suppose a and b are different prime numbers greater than 2. How many whole-number divisors are there for the integer \(a(2a+b)-2a^{2}+ab\)?

The expression has 12 divisors.

The first part of the expression can be written like this:

 

a(2a  +  b) ==2a^2  +  ab. Now, look at the 2nd part of the expression: 2a^  +  ab. Do you see any difference between the two? They are exactly the the same! So, no matter what 2 different numbers you enter, primes or not, you will always get "0". Unless you made a mistake in typing the expression.
