Question

Find the LCM of x+2 and x-2​

Answer 1

Answer:

x square -4=x square -2 square

by using the formula odd a square -b square

Answer 2

Step-by-step explanation:

First expression = a2 + a

= a(a + 1), by taking common ‘a’

Second expression = a3 - a

= a(a2 - 1), by taking common ‘a’

= a(a2 – 12), by using the formula of a2 – b2

= a(a + 1) (a - 1), we know a2 – b2 = (a + b) (a – b)

The common factors of the two expressions are ‘a’ and (a + 1); (a - 1) is the extra factor in the second expression.

Therefore, the required L.C.M. of a2 + a and a3 – a is a(a + 1) (a - 1)
