Q. The LCM of polynomials $14\left(x^2-1\right)\left(x^2+1\right)$ and $18\left(x^4-1\right)(x+1)$ is
Polynomials
A
$126(x+1)\left(x^2+1\right)(x-1)$
B
$126(x+1)\left(x^2+1\right)\left(x^2-1\right)$
C
$126(x+1)^2\left(x^2+1\right)(x-1)^2$
D
$126(x+1)\left(x^2+1\right)(x-1)^2$
Solution:
Factorize the given polynomials. The product of all the factors with highest exponents is LCM.
