Question

Find the least common denominator of 1/2x-6 and 2x/7x-21.

Answer 1

14( x - 3)

Explanation:

1/2x-6 and 2x/7x-21.

simplify (common factors)

`(1)/(2(x - 3)),(2x)/(7(x - 3))`

Find the LCM (smallest positive number that all of the numbers divide into evenly) of the denominators of those values

`2(x−3),7(x−3)`

Now we get

`14( x - 3)`
