Example 1 1. POOLS The accuracy of a pool thermometer is the positive difference between the
temperature reading on the thermometer t and the actual temperature of the pool
p. Write two absolute value expressions equivalent to the accuracy of a pool
thermometer.

npo

Step-by-step explanation:

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

here is a big fat
