Kiran and Mai are trying to figure out if this equation is an identity:
(a - b)4 = a– 4a3b + 62² 62
4ab3 + 64
Kiran picks several different values for a and b to test.
For each pair he tries, the left side and the right side
have the same value. Since his tests all worked, Kiran
thinks the equation is an identity.
Mai started by using the distributive property on the
expression on the left side. She then arranged the
result to look the same as the right side. Since she can
write both sides the same way, Mai thinks the equation
is an identity.
