Find the lcd of the pair of expressions.

8/5b; 12/7b^3c

a) 7b^3c
b) 12b^3c^2
c) 35b^3c^2
d)'35b^3c

(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

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
