By checking integers, we can find that the integers that satisfy this condition are , since , , , and , all of which are 48 more than a perfect square.
Steps
Step 1 :The trinomial can be factored over the integers if and only if the discriminant is a perfect square, where are the coefficients of the quadratic equation.
Step 2 :In this case, , , and . Thus, .
Step 3 :For to be a perfect square, must be a perfect square. This happens when is an integer such that is 48 more than a perfect square.
Step 4 :By checking integers, we can find that the integers that satisfy this condition are , since , , , and , all of which are 48 more than a perfect square.
