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 original equation a(2a + b) – 2a2 + ab
multiplies out to 2a2 + ab – 2a2 + ab
reduces to 2ab
since a and b are prime numbers greater than 2,
the only divisors of 2ab are 2, a, and b
so the answer is 3 (three)
.
Thx for your help, but that was incorrect.
