Question

How do you find the LCD of 12x , 40y?

Answer 1

See a solution process below:

Explanation:

We can rewrite `12x` as `color(red)(4) xx 3x`

We can write `40y` as `color(red)(4) xx 10y`

To find the LCD multiply the common factor in each term by the factors that are not common for both terms:

LCD `= color(red)(4) xx 3x + 10y = 120xy`
