The expression equivalent to n² – 26n + 88 can be found by factoring the quadratic. To do this, we need to look for two numbers that multiply to give +88 (the constant term) and add to give -26 (the coefficient of the linear term).
The numbers that meet these criteria are -22 and -4, since (-22) + (-4) = -26 and (-22) * (-4) = 88.
Using these two numbers, we can factor the expression as follows:
n² – 26n + 88 = (n – 22)(n – 4)
This means that the equivalent expression for all values of n is (n – 22)(n – 4).
