The number of ordered pairs of integers satisfying the equation is
Explanation for the correct option:
Find the required number of ordered pairs.
An equation is given.
Rewrite the given equation as follows:
Assume that, and .
Therefore,
Since, are integers. so, are also integers.
Which is possible only when or .
When .
Since, have two possible values each. So, also have two possible values each.
Therefore, the number of ordered pairs is .
When .
Since, have two possible values each. So, also have two possible values each.
Therefore, the number of ordered pairs is .
Thus, the total number of ordered pairs is .
Hence, option is the correct option.
