Which expression is equivalent to n squared plus 26 n plus 88 for all values of n ?

To factor n² + 26n + 88, find two numbers whose product is 88 and whose sum is 26. Those numbers are 4 and 22, so the expression factors as (n + 4)(n + 22). Expanding this choice gives n² + 26n + 88, so choice C is equivalent for all values of n.
