How do you find the LCM of #(3r-1), (r-+2)#?

Answer 1

Please Recheck Your Question...

Is it finding the LCM of #(3r - 1) and (r +2)# respectively

#(3r - 1) cdot (r + 2)#

Also be specific on this #(r-+2)# should it be #(r + 2)# or #(r - 2)#

To find the least common multiple (LCM) of (3r-1) and (r+2), we need to factorize both expressions.

The expression (3r-1) cannot be factored further, as it is already in its simplest form.

The expression (r+2) is also already in its simplest form.

To find the LCM, we take the product of the highest powers of all the unique factors in both expressions.

Therefore, the LCM of (3r-1) and (r+2) is (3r-1)(r+2).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
