The LCM is $(x-1)(x+2)(x+3)$

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 $(x-1)$ . $((x-1)(x+2)(x-1)(x+3))/((x-1))=(x-1)(x+2)(x+3)$
