Chapter 2 : HCF and LCM

Factors of algebraic expression is obtained and then common factor of the expression is collected. This common factors is the H.C.F.

To find the L.C.M. we find the common factors and then we multiply then by the left out factors.

Example 2. The LCM and GCD of two polynomials, P(x) and Q(x) are 2(x4 - 1) and (x + 1) (x2 + 1) respectively. If P(x) = x3 + x2 + x + 1, find Q(x) .
