Simplify the following :
373+353+283-3x37x35x28372+352+282-37x35-35x28-37x28 ?
Given 373+353+283-3x37x35x28372+352+282-37x35-35x28-37x28
It is in the form of
a3+b3+c3-3abca2+b2+c2-ab-bc-ca= a + b + c
Here a = 37, b = 35 & c = 28
=> a + b + c = 37 + 35 + 28 = 100
Therefore, = 100
If a - b = 5 and a2 + b2 = 97, ab = ?
