Question

9.
Find the L.C.M of (x - 1) (x - 2).
​

Answer 1

Answer:

Remember that you can find the LCM between two expressions by multiplying them, and then dividing it with their GCF.

(x−1)(x+2)(x−1)(x+3) is the product

Now, it is important to see that (x−1)(x+2) and (x−1)(x+3) share (x−1) as their greatest common factor.

Therefore, we divide (x−1)(x+2)(x−1)(x+3) by (x−1). (x−1)(x+2)(x−1)(x+3)(x−1)=(x−1)(x+2)(x+3)

Hope it helps;)
